If you like Farscape or iconing, and the excitement that friendly competition brings, you should check it out (even if you don't know what a LIMS is - the rules will shed some light on that, don't worry! ^^).
Or if you have no other reason to join, JUST DO IT TO MAKE ME HAPPY OK? :D Cause I kind of suggested this, so I feel it's my responsibitlity now to lure enough people in so we can have a nice long round :)
Iconers of all skill levels are welcome. It's probably most beneficial for beginners cause you get real advice there. And also I think pretty much everyone would benefit from the course to concrit giving.
tl;dr? In short, JUST JOIN IF YOU WANT TO HAVE FUN WITH ICONS. It isn't that serious so no need to stress about eliminations too much. ^^
