I notice most of the members are not putting links to their collections in their posts, so perhaps they're not getting the attention they deserve. (You can also click the web link to the left, but that's not as noticable). Here's how to do it:
Click "Profile" above.
Then click "Forum Profile Info" on the left.
In the Signature block, type this:
[utl=www.mysite.com]My Poster Website[/utl]
Be sure to (1) replace "utl" with "url" (for technical reasons, I had to use utl in this posting) and (2) use your specific website info. You can put anything you want in place of "My Poster Website" like "You'd Be Crazy to Click Here" or whatever.
Examples:
[utl=www.posternirvana.com]My Poster Website[/utl]
[utl=http://picasaweb.google.com/alphamel1968]My Wanted Posters[/utl]
[utl=www.mypostercollection.com]My Superfly Posters[/utl]
They will show up like this in your signature:
