Changing the Ticker

I have not posted for quite a while but I was wondering how you go about updating your ticker.  I have forgotten how I was able to first get the thing to display!  Plus it seems that someone has updated my signature line?  I did not think anyone else had access to it?  Any help would be appreciated.

I was able to figure it out...okay I guess I am not suffering from Alzheimers just yet!

alright, i am not suffering from altzheimers, but i am braindead, i cannot figure out how to put my ticker on... any help???  i made it, just can't get it from point a to point b.  thanks
