The problem is that the mod is not compressed.
.rar is the accepted format here.
To get it, go to
http://www.rarlabs.com and click download. Click the English version and install it. When installed, right click on the folder and click "Add to -Blank-.rar or if you want to give it a different name, click "Add to archive".
Once you have compressed it, go to the site, open a new thread and click "Browse", find the .rar file and click "Add Attachment". Type your message and hit post for all to download!
