[How to remove a mod]

Sadly although the modselect sounds like the right option that is for single player only, i dont know what you might to do in the server config files to remove it but i wouldn't doubt that it will take some time to get the removed.

[IC2 Teleporters Tekkit SMP 3.0.4]

On a community server with friends , I had noticed that teleporters do not work or are possible bugged? I have dedicated MFSUs to both sides, they are not set to emit a redstone signal, they are button activated, and they are linked, ive tried a few methods to fix them and no such luck. The teleporters do make a Blue " End like" cloud when iactivate the button but i do not get teleported and i also noticed that the MFSU doesnt lose any power.

Is this only because that they are bugged? possibly even just a issue with not having flight permissions on the server, also even though flight is disabled i can still fly in the normal world but not in the nether, thus i am leaning more towards just a bugged server than a simple fix.
