Forum posting characters incorrectly?

I just posted a reply to a thread here:

meulie.net/e107_plugjes/foru … c.php?6607

Therein I included an e-mail address I kinda made up, but in the post it displayed the “at” sign as the “C” symbol that denotes a copyright. Is this a method of protecting people from getting spammed? If so, I’ll edit my post…

Okay, just adjusted my post a little and it’s displaying the “at” sign now…
