If you display or post your email anywhere, you're kind of putting it out there by choice.
What personal information can guests access about you? Only what you post in one of the viewable forums, unless I'm mistaken...
I recommend that everyone stay as anonymous as they can (using alt email accounts created specifically for wedgie purposes, not giving out personal information publically ever, not giving out personal information over PMs, email, or other mediums until after you've established communication and taken reasonable safeguards, etc).
