There are ChangeLog files which have email addresses, but since they're not a standard part of every software project, and they're not always updated as part of the same CVS commit (and certainly weren't updated in the same instant with RCS), it wouldn't surprise me if the conversion tool didn't try to use them for figuring out email addresses.  And really, it would be much more of a manual process, since the email address and FSF account name don't necessarily have some obvious and easy-to-program correspondence.

I agree.. I was getting a bit mixed up with ChangeLogs.. it would have been good though difficult to try to use that info instead of 1:1 from CVS account, but not worth huge efforts now.

Thanks for the clarification.
