This project has been around for several years now and has been creeping forward since it's inception. It's certainly a great place for people to deposit little nuggets of information. Unfortunately, most of the discussion on the forum is about experience and not historical. When there are more scholarly discussions, much of the information never makes it to the wiki to get preserved.
It might help to promote the wiki on the front page. I've held off fearing additional spam. It might be best that only people who've been active in the forum know about it.
The wikipedia page on slings has grown substantially - where are those people coming from?
I have to admit that I've not played a huge role my self. However, I did put in a good deal of time writing a publishable paper, which I felt was best conduit to start correctly representing slings in the literature. I'm the only author claiming the sling could approach 700m! (2-4 times more range than most authors) I hope people start referencing the paper and set the record straight!
