The other day, I opened my email to find a wondrous surprise, I had won the May prize pack from The League of Extraordinary Writers. Yay. Books and swag! If you enjoy dystopian novels, I highly recommend you check them out. Plus, they get bonus points from me by discussing Joss Whedon's Firefly today.
Another blog and webiste I've been visiting frequently is QueryTracker.net. You can search for agents and it's instantly visible whether they accept submissions by mail, email, or forms. You can then save your searches and record the responses. Rejections get evil emoticons. It's fabulous. They also have frequent agent judged contests, but you have to be quick on the draw. They do, however, give you plenty of notice as to when the contest opens.
FYI, I don't post a lot of links on my blog. More often, I'll put them on my Twitter page. If you're interested, the link for that is on the side.
