"Welcome back," in a sense, since you sort of said you're not necessarily coming back.
Yeah, iNeedSpeed is right - many of the games are bugged, and the only game that really gets any attention these days is Creative - I haven't seen the server hit more than 100 players at any given time in quite a while, and the newer minigames don't seem to get played at all. I see a few people scattered around Murder every now and then, but I don't really see any progress being made.
The current staff say that good stuff is on the way, so I guess I can hope that things will improve in the future, but to be honest, I've been inactive on the server for quite a while, and I honestly don't see that changing without a miracle. Creative plots aren't really my jam when it comes to server minigames, and any kind of Murder on Minecraft servers have lost their spark for me ever since I started playing GMod Murder, which Minecraft Murder was based on. (I used to spend a ton of time in Murder on this server, but it's died down so much that I have no interest in playing!)
With the most popular minigame dying off and providing no interest to me, and the second most popular receiving almost no traffic these days, and the new minigames being completely empty, I simply have no reason to stick around the server. Most of the people on my friends list aren't around, either, so I just don't really bother anymore.
I like the community here on the forums, but people leave this place, too. It's kind of sad.
So, yeah -- don't feel like you have to come back. That's up to you. Of course, we'd love to have you, but we don't want to force you into it if you won't enjoy it. Feel free to stop by every now and then (forums or server) to chat.
