I'll do my best to explain this a little better.
The way that section is set up on a V2 profile (when converted to BBCode) is:
[li
st]
[
*][u
rl=www.gaiaonline.com/friends/add/]Add to Friends[/u
rl]
[
*][u
rl=http://www.gaiaonline.com/profile/privmsg.php?mode=post]Send a Message[/u
rl]
[
*][u
rl=http://www.gaiaonline.com/gaia/bank.php?mode=trade]Trade[/u
rl]
[/li
st]
Which, with the code RadioCarbon provided allows you to add images as well as hovers to them.
All you have to do is make a custom section set up like that and edit the code RadioCarbon provided with the appropriate selectors and images. I explained previously what the selectors would look like ( better explained in
Freaxy's Guide to Custom Sections). =)
