Hiya Pungacious, nice to see people taking such an interest.
While yes, horizons has been taken down, it was after careful consideration of the player activity, and level of completion within the mod pack. While we would love to have a server up and running 24/7, it isn't feasible to run such mod heavy packs on our system with such a short lifetime. For this reason, we're looking into a completely custom mod pack, which is still very much in the works, as well as potential other ideas.
However, were not a minecraft community, per say, and not are we hell bent for leather about becoming a huge community either. We're always happy to grow and expand, but we'd much rather be a community where people come to game and be social, than to look for one single thing.
For this reason, we actively encourage the community to say what we want to do (that means everyone has a voice, including admins) and if your idea is even remotely popular, we'll see what we can do. One member has a TF2 server that they run. It's not exclusively for this community, but that doesn't matter. The point is, it's there if people want it.
So, if you say you want a modded minecraft server, well, so do many others. We're working to build one, but without input from the community as a whole, we can't deliver exactly what you want. Yes, we had one previously, but it was too "run of the mill" too normal almost for it to last a long time.
So this is my challenge to you. And anyone else for that matter. If you have an idea, or a question, or anything really (provided it's not racial / hateful / otherwise illegal in some significant way) that you want to say; and can say it in a mature way, we'll listen.
No idea is a bad idea until we've heard it and evaluated how wrong it is after all .
I myself am looking into setting up some good old fashioned L4D2 nodes on a server, which I'll probably leave open to public access. Or at least, so that people here can hop onto it whenever. If you don't use it, that's fine. It'll be there if someone wants it.
That should iterate the point of our community here. We're a collective group, who work together to have fun together, whatever the mood. Feel free to chat to us, any of us, about anything, be it on the forums, on teamspeak, or maybe you're really too clever for your own good, and can find one of our email addresses...
Enjoy your stay, and remember, that we're always around; one way, or another.
