Here's a Forum where you can post pics of your newest TF2 Models which are under construction. You can post as many Pictures as you want, you only have to write the picture-URL down at the end of the Post then the Image will be displayed there. If you dont have webspace to upload the images, I can do it for you. You also can post models you're doing for a TF2 MOD, but don't forget to write down the MOD-URL!
The name of the Post has to be the Modelname and the Poster has to be the Modelauthor, if you don't follow the rules the Post will be deleted.
