This is very common for example when you are registrating your blog in blog directories or your company in site directories. I think it would be a very good idea to have this option at Buddy Press.
We would like everyone to be able to become a member at our social community for free, but that the members who like to add a link to their website has to add our link to their site first.
How can this be done? Is there any WordPress plugin for this?
We also would like to have a Business Directory (for companies related to our subject) working the same way.
Hope someone can help!
