Welcome back. With less than ten post to your name during your time with the November11 WolfPack, I'm not sure you know the protocol.
In a nutshell, you owe your former group an explanation. If you don't believe it to be true, read the posts below. People were looking for you. They were concerned about your. You left them dangling in the wind. Let them know why this time will be different.
You also owe your new group an explanation. They will be suspicious. We are suspicious. Everyone wants to know that the energy they put into watching your back will be energy well spent. Let them know why this time will be different.
In your case, I imagine the explanation should be pretty easy, almost self-explanatory, but you need to give it anyway. Whatever your do, DO NOT return to the slavery of the can. Are you ready this time?
