I was supprised to find google ads on your homepage. As far as I know this isn't allowed by sourceforge.net
You may not use your project web site to generate revenue, display advertisements or information about non-Open Source products, or to solicit donations except via the SourceForge.net Donation System.
This message can be found in the admin panel and then going to shell/DB/WEB
You might not be aware of this.
That's not what it says here:
"IF YOU ARE AN ADMINISTRATOR OF A PROJECT ON SOURCEFORGE.NET, THEN THESE SERVICE-SPECIFIC RULES AFFECT YOUR RIGHTS AND YOU SHOULD READ THEM CAREFULLY.
