Pop up?

Okay so I want to post something on one of the moutainbiking forums I go on, I click post and this poped, Wtf dose it mean?

probably a extremely over senstive filter system.

If you included things like < > then it might think "OMFZ!!! someone trings to hack my page with html!!!!"

so then it might not allow your post and mark you down as a hacking attempt.

just a idea.

It still posts it though, that just pops up. I thought some one was trying to hack me :p
