Oh, so your saying you saw somebody doing this?
If you want the fellas that run this place to take care of it, then you should definitely post the photo.
I'm not the one to show it to though, and I'm pretty sure there is no way to prove that someone is using 2 accounts on 2 computers...
For example, me and AgentP are sometimes on the same Ip when he's here, which is 2 people, 2 computers, 2 accounts ;)
