's version does have a list of all the SEXPs and describes the functionality of every checkbox and option in the editors. Why not update these aspects?
Updating all the new SEXPs in a seperate section at the bottom of sexp.html won't hurt a bit and should show newbie FREDders why we all love FRED2_Open so much.
I'm a little more worried about updating editors.html because
a) Much of that stuff is way beyond the abilities of someone taking their first steps in FRED
b) I can envision a situation where someone spends ages looking through their local copy of the FRED docs looking for the entries they swear that they've seen before
Of course if we're talking about porting the FRED docs to the wiki then b) vanishes cause the look and feel of the docs will be rather different
I was assuming we'd simply be sending them over to Hippo cause he's already got them all online.
