Redstone circuit restarter in SMP?

[FrozenToast2]

Is there any way to restart a pulse repeater circuit with a button/switch? I need something like that for my new cobble generator, but I wouldn't know how (on google I only found some for SSP).. but I'm quite a noob in redstone so any help would be appreciated (:

Ye, you could use a pressure plate trololololol.

well im not quite sure what you mean, but there is no way to make a signal start as soon as someone gets in range or something.

use redstone torches, they dont bug when you go out of range :d
