It has come to my attention that some are having a problem with changing their profile.
So, here is a step by step on what does what.

1. Click on the profile link at the top of the forum.
You are looking at the profile home. This part is pretty much self explanitory.

2. public This shows you all your public information.

3.Regestering
This shows you your username, email addy, and is where you can change your password.
A screen shot is here

4.Profile
This shows you your board setup information.
[in the subbox on the left]
A screen shot is here
privacy...These are your privacy settings. (show me online, show sig, etc....)
A screen shot is here
Notification...is email and pm settings
A screen shot is here
posting...show sig, allow html/bbcode etc...
A screen shot is here
reading...avatar settings.
A screen shot is here

public information....There are 3 side links here.
A screen shot is here
web information....website addy
messengers....icq, msn, etc settings
personal information...real name, gender, birthday, etc....
A screen shot is here
That's it for the left side bar in the Profile area.

Now, back to the top, next to "your profile" are several links.

Preferences...set your buddy list, pm, watched topics

Signature...Is just what it says. It is text that you can place here and whenever you make a
post, it automatically adds this to the end of your post.
avatar....choose your av.

Back to the very top....
next to "profile" is buddy list...this is where you can add "buddys" (I don't use this. Don't
even know what it is for,actually)
Private messenging...This is just a link to your private messenger.

Hope this helps you out.
