Hi milkabum. Wellcome to the Dis. My sig was created by the sig fairy. Here is a link.
http://disboards.com/showthread.php?t=859672 just post that you would like a sig and in time she will get you one! For the avatar you need to go into your account and click for the avatar. I'm not computer savvy enough to know how to personalize your avatar, but I'm sure others here can help. Anyone?
there is a Technical support board. There are stickies there to explain how to do it and people there who know how to do those things.
if you have any other questions for me, just click on my name and click on private message. You can send me a private message that way.
