What are all the tags for everything in the profile? I know that these are the forum ones.

Bolding:
Italics:
Centering: [Align]
Align left:
Align right:
Image:
Underline:
Subtext:
Suptext:
Strikethrough:
Clickable link: [.url][/url]
Clickable link text: [.url=link]text[/url]
Color change:
Font size:

Everything is []text[/].

its just the same in the forums except u cant do url= and img= and maybe bold italic and underline
maybe only resize color img and url?

If I remember correctly, the tags for the profile are the same as the ones in inbox/private messages! So you could use your inbox and compose a message as a way to set up what you want on your profile. ^^

You are a saint.

For making url links in profiles, instead of url=, it's urllink=

I don't know if there's an img= equivalent, I usually just use a mix of urllink= and, instead of writing text, I just put a "img" tag and that's how I put things in my About Me

I heard that you can "compose" a blank message in your Inbox to test if your tags works correctly, as they use the same system for About Me and messages
