Hi mofo! Thanks for registering to the new forums
To answer your question the old and expired contests are still listed on the main site (http://hitechlegion.com/contests-and-giveaways
). When a new contest starts up you will see it on the main page and in the Contest section here in the new forums.
Feel free to post around and help us build the new forums back up and make them even better than the old. You can start off by sharing your thoughts on the new forums over in the Welcome thread: viewtopic.php?f=2&t=1
