Be warned if you do use IdResolver, if you have to update in a couple of months & use it again the ids will not be the same so all maps will be null & void, its better if you take a look in the configs & manually change them, like portal gun only a couple to change, then if you need to update you maybe able to copy over your old config & minor edits as needed, plus, if your going to run a server the pack is only part of it, you need to manually install & setup a host of software to control, edit, & balance your server, & then sofware to stop griefers, so my advice would be to research a lot or wait until CreeperHost start there ftb pack hosting.
anyway gl with your endeavorers.
