EDIT: The forums are unlocked. Happy reading and reviewing, everyone :)
The Jan/Feb Review-A-Thon begins in 1.5hrs. I will open the official threads then, so you may review and post your links.
If you wish to sign up, you may do so by going to the forums and posting on the sign up thread. You may enter at any time during the 4 weeks, as the winner is determined by how many non-one liner reviews are made, within the 4 weeks the competition runs for :)
Have fun, and good luck :)
