Confusing feature names
During testing session #788 (closed), users noted that they found the names of the current features confusing.
Forum and Private Groups
Users noted that forums seem to resemble what they know as groups from other messengers (WhatsApp, Telegram and Signal) due to them being open in the sense that everybody can invite new members to the forum/group. They suggested to maybe call it "Open Group" and "Private Group".
After understanding somewhat how Blogs work at the moment, the testers agreed that blog is not a good name for this feature. They suggested to call it "Timeline", I guess mainly because they couldn't create additional blogs and because everybody's posts were shown in this list like they know it from Facebook and Twitter.
