[OT] Fix the forum editor

OffTopic - I coudln't find a specific place to post questions about this community itself.

I've been using online forums since pre-Y2k. I've just registered here and posted some messages, using the latest Chrome browser. The post editor has some really annoying issues:

1. There's no undo. Ctrl+Z doesn't work. WTF!?
2. The browser's spell checker is disabled.
3. When Alt+Tab-ing back to this window, the depressing of the Tab key will be interpreted as a Tab, and it will indent bullet points like this.
