Hi,
This is a very simple plugin for sign elevators, based on some plugin from the great Beta 1.7.3 days, the name of which I don't remember.

To create an elevator, create a sign with [elevator] on the first line (can be changed in config).
To create an elevator for another player, type their name on the last line of the sign.

To travel up, right-click the sign, to travel down, shift-rclick the sign.

The plugin requires Vault, as it supports economy - the creation of an elevator can be paid and is set to 100 by default.

Permisisons:

Use: simplesignelevators.use
Use other people's elevators: simplesignelevators.use.others
Create elevators: simplesignelevators.create
Create elevators for free: simplesignelevators.create.free
Create elevators for other people: simplesignelevators.create.others
