I am afraid that I have to agree with not giving out that info.
I do not believe that having real names posted on the WEB for just anyone to see is a good idea at all, and I would be against the idea.
For deals / transactions I give out my first name all the time, and quite frankly they get my bank account / address if they deal with me anyway so people do have recourse if a deal goes sour.
I would not want my full name posted under any circumstances. First name with last initial for transactions MAYBE.
But again I don't think that it should be mandatory.
Just my two cents.
