It's basically a search string based on started threads in a particular forum. If you hover your mouse over the appropriate subforum link on the main forum page - (forum.cartographersguild.com not the main entry page cartographersguild.com) - it will tell you the forum number in the lower left (Firefox) so that you can change the search to whatever you like. You also need your ID number so hover your mouse over your name and look in the lower left of the screen.
The link looks like this - the site upgrade won't let me post the whole thing without screwing it up so make sure to add the http:// and for some reason it keeps putting a space in forumchoice (apparently it always puts a random space somewhere in a long string as you can see in my underscore line - I wonder why it does that) so take that out.

Finished Maps is 36, Tutorials is 48, and Challenge Archives is 59
By using the search string for challenge maps I can avoid filling up the Finished Maps section with my old challenge maps...sure it finds all threads started by me and that will include actual challenges and polls and whatnot but c'est la vie.

Hmm, no matter what it keeps putting a space between the c and h in &forumchoice[]...how weird. Of course now it doesn't do it...forumchoiceforumchoiceforumchoice...damn thing. At any rate, just hover your mouse over My Maps there and it will show the link in Firefox in the lower left or right click it and choose properties.
