[EDIT: Ichnowiki is no more. 2014-02-11]
Ichnowiki will be offline for a while, as I have had little opportunity to add information or to promote it, and it makes me feel bad to leave the computer in my office running all the time “just in case” I should have the time to do either of the above.
If you are searching for something like Ichnowiki, I can let you see what I have so far if you ask.
