It's not purple all the way, it's only in the online list.

You can't access the hidden beta tester section if you're not in the beta tester usergroup which will turn your name purple. So no. But if you can get somebody to keep you updated with download links of newer versions, I can remove you from the usergroup so your username isn't purple.
I'll add you both to the list.
FYI, nobody so far has submitted their log file. And no one of them will be credited either.
