An update!
For those of you who are working on your maps or finishing them up, or maybe even just starting them, and are wondering "man, should I make a video trailer for this map?" ... I'll gladly spoil the answer for you. It is yes. We encourage you to make a trailer for you map. Additionally, if your trailer is of a high enough quality (as decided by tf2m staff), and if you so choose, we will upload the trailer to the TF2M official Youtube channel. Please keep your trailers below 3 minutes.
Also, I'm looking for judges for this contest. Please PM me on the forums (not on steam, I will lose them!) saying that you are interested. In the subject line of the forum PM, please say something to the effect of "I'm interested in being a judge for the Dynamic CP contest!" ... something so that when I go through the conversations later, I can easily find those interested.
