Kacie Redux: A site mod? Click on "About Wireclub" below, click on "Our Team" and all the mods are listed and those online (if any) are noted as such. I've had mixed results finding one who will respond promptly, but I did get a room closed within 20 minutes once (and that room warranted being closed.) I have always just pm'ed on online mod.
GeraldtheGnome: Most of them hide when you require help from them. If you can find one on this site that actually does what he or she is supposed to do then let me know. Good luck with that.
