You can if you feel like it. And e-mailing an adming is a great idea since I don't think many people will see your article and realize that there's a L group.
i do not have the power to put it on the main page, or do not know how. i think that moderator (jim/heyrocker) has to put it there. i will email someone. i will add your country. should i add your favorite artists that are on your last.fm page as well?
I think that just group owner can add connections to group. If you can, please add Croatia to that list since I'm not getting the drop down box. BTW, it would be a good idea to somehow put a link to this group on Listology main page (if that can even be done).
