I would like to suggest the following: Please make the request for a CV optional. There are two reasons for this: First, many members are not English speakers so their CV is not written in English. Rewritting your CV may be a hassle for many of us. Second, some members (including me) would not like to publish their CV. They'd rather give it to anyone who asks for it, but they (I) would like to know who reads their (my) CV right now.
I have noticed that you have sections about the abilities of the member. Don't these sections cover the obligatory need for a CV?
