You're welcome to ask (since all staff members can give emblems) but don't expect it just because you decide to switch accounts. Mods do have other stuff to be doing than re-handing out emblems. :P
As for name changes, when we first decided to get rid of the system we talked about alternatives, ways to keep it around without straining the server, but we couldn't come up with anything.
I think one of the biggest problems is that people on PC changed their names the way they changed their avatars or signatures, it like a fashion thing. Usernames should be your identity. That said, I get that some people regret the names they've chosen and want the option to fix it, and for cases like that I'm fine with looking at alternatives to name changes. But for the people who literally counted the days until they were able to change again and changed on a whim... I don't want the hassle of it. :/ It can be confusing, it takes a lot of time for admins (those threads got riiiiiidiculous), and overall just messy blah blah blah.
So yeah, I'll brainstorm.
