As for acquiring artisans, have patience. Some sales require a minimum period of membership. You have joined, so it's just a case of participating in discussions until the time has passed.
In some sales you might get lucky first try. Or you might enter a few sales without winning anything. This happens a lot, and is nothing to be discouraged about. There are so many artisan keycaps out there that it is impossible to own them all! Just have patience, save your money, and you'll be ready when you do get lucky!
