Quote from Don Bright:
I think my answer was at least as clear...LOL (...AND IS NOT AUTOMATICALLY CONSIDERED A PROFESSIONAL EVEN THOUGH THEY HAVE BEEN REGISTERED. ....They still may be a professional because they meet the criteria in other ways)....???? OK, that's as clear as can be, yeah, sure, ok... (don't pay unless you think you should, let your conscience be your guide, I guess).
Happy New Year, again...

Yeah, it's still not 100% clear after reading the second sentence you quoted, but the language in the first part of the capitalized sentence makes it sound like you are no longer considered a pro if you get a U-5. (I think so anyway)

Regardless, I think I have enough justification to claim I'm not a pro.
