@
ichitaka05, I'm just testing the mention tag to see what it does.
Edit: Okay, this explains the "@bestwheelbase" I've been seeing at the beginning of some peoples' posts. old greg, when you're creating a reply -- there's a new icon up where you can make text bold or italicized, it's over on the right and looks like a loudspeaker. If you click that, it adds an opening and closing MENTION tag. If you type someone's username inside those tags, it will automatically throw the @ symbol in front of their name. I guess it's to clarify who you are talking to, or to bring a thread to someone's attention (since it will show up in their profile page under the Mentions tab).
Hope this helps.
