now all we need is a plugin that is similar to the trade sign but instead of giving or taking items it gives off redstone power just like a button (i might try to make it myself using the tradesigns as a base)

 

can you keep walking in and out of the area and only pay once? :D

 

no, you can not

 

The problem is, I'm not paying anything to spectate a spleef.

 

you can use it as a way for people to pay entry fee
it can be used in a lot of ways

 

Hmm, seems interesting, lets see what Andrew thinks :p

 

yes and if i know exactly what plugin the trade sign is i can use the source to create one for redstonepower

 

This is amazing :D
You could charge people to enter your hospital, even your town! like people that live in the town get an "easy access" door where they dont pay and visitors pay a "spectate" fee :]

This is awesome >.>

 

Well it would have a new thing for residents (Being able to set your home there to not pay) but for those who aren't residents, or have to set their home elsewhere, it would get really annoying, and even might make people just stop using portals...
