I would even support this retroactivly, even if only as a one-time way to grandfather in existing users. Even if it meant recalculating XP totals in an approximate way.

Yes it was orignially the same codebase, perlmonks was forked off of everything2, and there have been many new features traded in both directions since. I would be happy to contribute any changes, if the dev people didn't have time for it. THough I doubt that's ever the case around here! lol
