There was a change in v0.88t in how the ChatLogs menu works.
First, what is the ChatLogs menu?
It's the menu that's after Docs that confuses the hell out of a lot of new users. And rightly so. When you first start out there's just one item in the menu. It appears both in the title of the menu, and it is the single checked item within the menu itself. There's no point even pulling the menu down because there's nothing you can do with it. It's just standing by for the day that there are other chatlogs on this server that you can participate in.
One of the cool things about 1999.io that I hope people use, is the ability to have group blogs. That's why they're called chatlogs, btw.
So if the day ever comes that you can participate in another blog, then the menu will re-appear, listing the ones you can participate in. And then when you choose different items in the menu the context will switch.
There is only one owner of each chatlog. He or she is the only one who has access to the Settings command. But other people can create and edit new posts, and reply to posts.
