This functionality may already exist, I just haven’'t tried groupchat much yet as I am still deploying. I would like the ability to have invite only group chats, where only invited people are able to enter/join. Additionally I would like to be able to invite people into any chat, private or otherwise, to simplify the process of finding it. Having a link saying “you were invited to join group_chat_name, click here to join”. Would be easier than navigating through other means.
I must say that the one test I did of group chat made the step of finding group chats on the server through simple navigation much easier than other IM clients I have tried, so you’'ve done well in that area already!
One other wish item would be the ability to drop a file in the group chat, and thus make the file available to everyone there instead of manually sending it to the individual users present.
If I think of anything else I will let you know, I haven’'t used it enough to have many wishes!
Thank you for wanting to make this the best, and I look forward to a linux version !
