topics and nicks

hello ppl!

antville rocks.. however i have a few problems..

how do i edit the list of topics? right now our blog has a bunch of BS topic names that I really want to edit, but i don't find any possible way of doing this...

and how can i change my nickname on the blog so my name is still connected to all the stories / comments etc that i have posted?

thanks a lot for your help..
