What is OT ???

I see OT in many subject lines but I do not have a clue what it means?? I'm sure it is something very simple and I will feel like a goober for not knowing!!! Thanks Tonya

Hi Tonya, I think it means "off topic" that is what I use it for...u r not a goober, I hate to admit this but I didn't know what LOL meant for the longest time...lol Angela
