This seems like a very basic feature that should be there by default but it is limited to users paying thousands a month for enterprise or professional licensing. Manage custom groups (beta) — Mattermost documentation
The ideal size for Mattermost Team Edition is up to 50 users, and the system probably continues to work fine up to a couple of hundred.
As deployments near or exceed this milestone, our intention is for Mattermost champions to find the right capabilities in the commercial versions in order to developer a business case for purchase, to bring on the commercial capabilities and to scale smoothly and reliably.
Custom groups helps our champions build a strong business case for joining our commercial community.
You can learn more about our commercial versions at
https://docs.mattermost.com/about/editions-and-offerings.html
There’s also guidance in the docs for contacting the Mattermost customer teams who can support our champions in making the business case to their organizations.
Thanks for asking @lpnc_it. Does this help answer your question?
We’re a relatively small political party and while we like what we see and get use out of mattermost, we can’t afford to pay even a fraction of the per-user rates as published. Most of the members pop in once every couple of weeks or months as they volunteer or gear up for a meeting or event. Every dollar is donated. It appears we are excluded from the non-profit pricing as a political entity, so we have the price options of $0/month or $900/month.
My point was simply that this is a basic feature seen on slack, discord and other competing options.
