Hmm that would actually be a good fix for this here: https://community.nodebb.org/topic/6582/cooldown-on-group-join-requests/1
Chat only for selected groups
Right now I have two options: to disable or to enable chat. But I cannot enable it for certain groups and disable it for the rest of users.
Would be nice to be able to select which groups can use chat.
The way the permissions system works right now is based on categories, so at the moment this isn't possible. But it is an interesting idea, so I suggest you submit a Github issue.
All right. Thank you very much!
@alejandrocobo have you submitted the issue already... that e did you see any development on this?
Chat is a global privilege now, you can disable it for some groups in the ACP.
