This is a continuation of a post in the Forum FAQ:
My idea is to have the chat embedded in the forums, so I don’t have to open another tab to watch the chat while I browse the forum. This will be less of an issue once the new chat is released - it has notifications, so you don’t have to check for new messages regularly. Still, it would be nice to have the chat available here.
@LFP6 Now that I think about it, it does make sense to float the chat relative to the edges in all scenarios. I think I came up with the idea to position it relative to the center before the new site was released. In the old site, the chat was in the sidebar, therefore positioned relative to the page content, which was (and still is) centered. I’ll still probably want to save the positions for forum, in-game, and normal site separately (but perhaps make forum and normal site the same if one is specified but not the other?).
