Simple explanation <cough>:
Allows you to create easy two-way portal locations between worlds. With this plugin you can create a named portal, click on a block at one location, then click another block at the second location. When a player physically activates the block through a pressure plate they are transported to the other location.
Portals work in matched sets only. i.e. each portal only has two locations however you can create as many portals as you would like.
Here are the SIMPLE steps to create a portal with EasyPortal:
walk on the pressure plate and enjoy!
