Hi,
Let me start off by saying I am amazed by this piece of open source software. It truly is amazing. I was looking around the site, and I couldn't find anything about the specifics of what you can and can't do with this. Can you remove the Powered by opengoo on the bottom if your company will not allow another link on the bottom? I mean I think since it's open source you should in most cases, but once in a while that won't swing with the specific project or company.
Also, if you're a freelancer, can you charge clients to use a copy of it if you host it on your server with their site?
Thanks
