See, I read your question relatively soon after you had written it, sartorous, but I decided to take some time to think it over... to sleep on it, even, hoping to come up with the fairest, most diplomatic and reasonable solution for this matter for you, the other players, and myself. It took a little time, but I think I have arrived at an acceptable compromise for all parts involved. You can decide freely whether you want to resubmit Salas or a new character, although if you return Salas you will need to have a believable explanation ready as to how he survived and escaped the Anaxim Forest... [I]IF[/I] you agree to the following terms.
One: If you take more than 48 hours to reply to this post, that's an automatic, unnegotiable "no" and will mark your permanent departure from The Prophecy. Taking a while to post IC is completely understandable considering the quantity and quality that is expected to be written, but checking for new posts can be done in a matter of seconds, and a quick OOC remark can be made in a couple of minutes. When you ask a question as important as "may I rejoin this RP?", I would say that it is common courtesy to check back quite often immediately after asking it and replying to the person giving you permission. Last time you never really did that, and we didn't hear from you for over a month after you asked if you could rejoin. That is unacceptable, and if that is going to be standard with you the RP will do without it, because that is aggrevating to me and players possibly being held up waiting for you.
Two: You must swear to that you will [I]never[/I] simply disappear again. If you are going to be a player that just drops one post every several months and then disappears off the face of the world in the meantime, as you have been thus far, the RP is better off without you. Players and myself have waited and been delayed immensely several times waiting for your replies that never came, and I won't have the enjoyment of other players sacrificed for the participation of one player. If you can't be as active as usual for a while that's fine, we all understand that real life must be the first priority, and we all let ourselves be delayed by it from time to time... but once again, dropping a quick OOC remark to let us know of this circumstance takes neglectable time and allows us to compensate for your absence rather than just wait impotently for progress in events that never occurs.
Three: When I ask if you are still here - and you will be included in "everyone" - you will tell me if you are, or I will assume you've left and remove you from the RP permanently. I'm fair when I ask and usually give relatively long time to respond, but expect a response I do. If you can't even drop a "I'm here", I'll have to assume that you aren't here.

I may sound like an absolute ass, but I can't simply say "welcome back" and let you rejoin unconditionally anymore. Your activity, and the way you have announced your absence - or rather, the lack of announcement of absence - has been unacceptable, and when a player goes missing like that it affects everyone else in the RP. I need to know that this won't continue. I'm sorry if this discourages you from participating in the RP, but I have to set the RP itself above the individual player. Accept the terms and you may rejoin; if you won't or can't, you may not.
