Hi! I've read through the Community Guidelines, but I'm a bit confused about the personal information bit. Am I allowed to mention an email address which has no personal information on it about me, to email Scratch files for collaborations? Thanks

It's heavily debated, because using that email, you could get ahold of another scratcher's email address. For now, try to only share it with as few people as possible (or preferably, try not to share it at all).
I know for sure that specifically sharing your email with EVERYONE, like putting it into your signature or About me, is not allowed.

The ST doesn't allow email addresses to be shared and stuff. It's too crowdy for us to tell the answer.

I wouldn't… I got docked once for giving out my TOWN. Not even my street, just my town and state.

OK, thanks everyone I'll just play it safe and not give it out then.
