... Unless you like spam. But I don't think you do.

Here's the deal: Spambots are peeking at the discussion forum, taking down your emails and setting it up for junk mail. That's no good - I should know. I had to change emails quite a few times in the past. (Personal Note: Microsoft is junk about junk mail. No proper settings. Gmail is better.)

So: Don't include emails! PM them instead. :)
