I can do both of those things with the threads, if you're absolutely sure?
As for the name change, I'm pretty certain they've been abolished again- you may be aware of what I'm about to say but I'll say it anyway just in case. Basically, name changes were quite hard on the server, and so eventually they became an impossibility. Recently enough they were tested again on one or two moderators, but after the last one apparently it caused the site to crash again, so they've been abolished, again. That's as much as I know about the situation, anyway; if you want to change your name I think all you can do is make an alternate profile and link to it from here.
