It has only been two days since he was last logged onto the forum, WeirdRaptor. All I can say is be patient. People do have other real life issues/things that they have to tend to and will not be available on the forum all the time, although I think you definitely realize that without me telling you. Tell me, has the PM conversation been constant from Day 1, like at least one PM from him a day? If there were times that he hasn't responded to you for days back then, it wouldn't be too weird for it to occur again. And besides, I'd think you would have other ways of contacting Nick if you're really worried about him, since you have a pretty close relationship from what I've gathered from this post. Also, have you contacted other admins about the whereabouts of Nick? I assume that you wouldn't post a thread like this unless nobody knew the answer to that. Even if he didn't tell you anything about leaving/not being active beforehand, generally it doesn't raise any sort of concern unless the absence is prolonged for at least one week or more in my opinion. So yeah, don't fret about it. He'll return pretty soon, no doubt about it. The only question though is when he'll return.
