This site is using a few ways to do Wiki words, one is to use the Wiki module for extra explanation of things, and this will provide a new page from any words you surround in brackets [-[ across the Forum, Downloads and Articles; at present, maybe more if needed..

Then also we have the ability to use the Folding Items when we need, so any post can fold up as you are writing to then expand, as the reader chooses an option you make. That take a bit of html knowledge in closing div boxes, yet isn't that hard to do and can look cool.
