Make a second server alongside the original.
Tekkit adds too many things to be the main Minecraft server and leaves out the people who don't like having mods all over the place.
And don't you have to download something to play it?
I am not sure if you have to download something to play it, but it wouldn't be too hard to set something up on the forums and direct people there to play it, I'll look into that
Thing is, reg minecraft is not cutting it at all, seems like everybody plays for a good month, then is gone. Minecraft can be a drag once in a while, but I'm looking for a steady population, not something that just burns out and Tekkit seems to add so much that it tough to get bored, plus it will set us apart from other regular servers.
