We now have a new wiki tool to use which should be a 1000000x better than our last one. I have a made a how to doc on how to use it but basically here they are in brief.
wrap wiki [WIKI]bbcode [/WIKI] around a word and it will create a new wiki page
when creating or editing pages, use the H [WIKI]bbcode [/WIKI] to make it a heading.
use h=1 for level 1 h=2 for level and so on.
If you have at least 4 headings a table of contents will be automatic.
To get there, click the WIKI drop down in the navbar above.
Post if you have any concerns or questions.
