Can you change your username on this site?

Also, I uploaded my signature to this site (it's 240 pixels tall). Why won't it show up on my posts?

Yes you can but you have to buy an add on of 1200 TBT in the shop.

Direct uploading has a limit of 100 x 500. You should use a third-party hosting site like imgur or tinypic if you have a signature that large.

I use tinypic to upload my stuff on here.
