Ask me (Tiraspriith/Yrsmgor) or Spektrenaad about Swagbucks.com. It's a search engine that awards you points as you use it, and those points can in turn be used to redeem rewards, one of which is a gamecard you can use to buy diamonds. The engine turns out the same results as google, and all you need to sign up is an email address, a name, and a password. Extra points can be garnered through a daily poll, watching videos, and completing offers (ex. they might make a contract with netflix and offer you x swagbucks if you join through them). The $20 gamecard is worth 2150 swagbucks and the $5 gamecard is worth 550; you can expect to win anywhere from 1 to 100+ points a day, depending on how often you use the site and how lucky you get.
NOTE: Make sure to ask me or Spek about referring you (you'll need to supply your email, so we can send the invite). This will (I believe) start you out with some bonus swagbucks.
p.s. I've put up a notice on the ingame guild announcements in case anyone ever looks at it.
