Just a quickie since I'm still at work...
There currently are no rules regarding role-play relating to the on-site chat - be it for, or against.
Speaking of this issue, a number of reports have been filed today regarding chat conduct, both by those that are in favor of role-play in the chat, and those that are against it. These reports will be dealt with in several hours when I get home from work; during the process of which I will be doing a lengthy review of today's chat logs.
At any rate, I just wanted to toss this reply in so that you're all aware that WE are aware of the situation, and that we will act on it.
