How do you sticky topics and make sigs? Please help me out. Is it the same style as vBulletin?

I believe so...

To make a thread a sticky, either go to the Moderation Options at the bottom of the page and choose "Stick/Unstick Thread", or from the forum display page, select the thread with the checkbox to the right of the page for that thread, scroll to the bottom of the page and select "Stick Threads" and press go.

To edit your signature, just go to the "User CP" and choose "Change Signature" from the nav menu on the left. Then, just use MyCode (BB Code) for any styling.
