Arbiter, I was sitting next to Wrenz as he was talking to you on Vent. Thus I heard your conversation and saw him talking to you about the raiding before then over in game tells.
As I noted above, I'd like us to chat directly later in this week, when you are not running an instance so we have your full focus, and come to a collaborative resolution on this. Wrenz asked you to please get back to him on what you had decided about whether you wanted to continue your PUGs or switch over to the main raid once we were ready; if you had talked to him rather than posting in here, I think this misunderstanding would have been swiftly nipped in the bud.
This is one of the reasons I am not a huge fan of forums as a means of guild communication as I have seen this sort of miscommunication escalate a number of times.
