It didn't for me... But I don't want that changing any time soon either. Plus Ephi's account uses gmail too, but he's special anyway. Are you blockheaded if you register with a non-free account then change to a free one?
Plus I think he means "re-join blockland with an email that isnt from a free email provider (i.e. gmail)", as in re-join the forums with an email that isn't from a free provider, eg gmail - Meaning that the free provider he is giving an example of is Gmail.
