for most small company, there is no ldap servier or sso. but all most have email service, self hosted or saas like google mail.
if there is a authorization type called smtp authorization like oauth2(google,gitlab...), it will make company helpful more without make another authorization system, bothered with account management.

We are using mattermost at our university and have a whitelist set-up so only people from our university can join. However some teams have indicated they want to cooperate with others who are not officially affiliated with our university and thus have no university e-mail address.

We would like an option for sysadmins to invite these users to the server.

This feature is really usefull to identify and follow different conversations in a channel.
When you click on a clock, it adds the clock in the beginning of the post (or at the position of the cursor).
When you hover on a clock in a post, it highlights the referring post and the answers to this post.

You can see a demo there : http://sveetch.net/tribune/

Provide Channel description in tooltip in the left panel

Currently, we need to go to the channel, then click on the little arrow, then View Info

Personally, I spent 5 minutes to find this kind of information when I was checking that I didn't miss something and it is not yet available somewhere easily

I have the team version of Mattermost for a small project with friends hosted at my house. The best way to notify my group is via email, however, I can only send so many emails a month through my SMTP server. It would be nice if there was an option for sending a once a day notification added in addition to the instant, 15 min, and hourly.

It would be also really helpful if I could set this as default for all my users and let them change it if they need to.

Markup to directly navigate to the ticket on Redmine, a small overview of the ticket as well. For example, when I refer to a ticket I use #ticket_no. This could be parsed by the parser and replaced by an href that points to the ticket

Currently I cannot find a way to know for which channel has been configured an incoming webhook (in my case, for integration with GitLab).

In the "Integrations/Incoming Webhooks" section, just appear the name of the webhook and the webhook URL it self, without saying for which channel has been set, and the option of deleting it. And in the GitLab side there's no way to know for which channel will be triggered the hook.

This come become a problem when you have several webhooks and channels.

When there are multiple teams, when a new post is made to another team, it is difficult for users to notice it. I want you to show it with an impact that would reverse the color information of the icon.
The same can be said for the channel name display within each team. It is difficult to understand with the current bold display.

Words not in the stock dictionaries are always marked as errors; there's no way around it.

Many "normal" users have problems writing markdown when chatting.
For example, my friend don't know how to add "In-line Images".
So, I want to send him a link to "In-line Images" section at https://chat.ohze.net/help/formatting
But I can't because "In-line Images" is not an anchor like, ex https://github.com/mattermost/mattermost-server/blob/master/CONTRIBUTING.md#stage-1-pm-review (auto added by github for headings in a markdown document)

Ability to use a generic 3rd party OAuth server for programmatic logins to mattermost server (team edition)

Please see for detailed description:

A simple image editor for uploaded images. This to draw lines, write text and add arrows. Would be great when explaining things. As in a quick bug report.

I'd really like to see the emoji picker that can be activated as described in the title, instead of the ":" followed by minimum of 2 characters as it is at the moment.
I'm aware of the full picker ticket https://mattermost.atlassian.net/browse/PLT-2354, but as i understand it doesn't include this feature.

The installation should be only depending on a ftp-access to a hosted server storing data in flat files. Second best would be mysql connection.

It would be really helpful to be able to specify a whitelist of IPs or accounts that can bypass the API rate limit. For instance, I use the API to batch-create lots of user accounts, which generates a high volume of requests. Yet, I don't want to allow such a big volume for any user account/IP address, just for sysops and localhost. Would this be possible?

An outgoing /slash command from mattermost sends information including the token, userid and username in the POST.

We would also like to see userrealname in the POST, without having to do another API call.

For example:

channelid=cniah6qa73bjjjan6mzn11f4ie&
channelname=town-square&
command=/somecommand&
responseurl=not+supported+yet&
teamdomain=someteam&
teamid=rdc9bgriktyx9p4kowh3dmgqyc&
text=hello+world&
token=xr3j5x3p4pfk7kk6ck7b4e6ghh&
userid=c3a4cqe3dfy6dgopqt8ai3hydh&
username=freddy
userreal_name=Fred+Smith
