It's no problem! All you have to do is use the "Report Post" icon (the little white triangle with red outline and a ! in the middle of it) and a message will go to the admin team and someone who has powers in that particular forum will remove it as soon as they can.
It's not considered an infraction here.....mistakes happen. Stuff like this happens all the time on a large forum site.

You're all good!
Oh, and btw, the admin team a pretty cool peeps, their barks are worse than their bites....

Seriously, it's all good!
