Yah... The thing is Mark documents all his stuff on his own site so there's not much need to mirror it, I might as well just put a link in there. Then new geeks who don't visit the BBS would at least be pointed at the hijack page. Also, things in Hijack change so much that it might get outdated by the time I finished updating it.
But when (if?) Hijack development ever slows down and the features seem to be "locked in," I will definitely document them. The first thing I will probably put into that Hijack section Real Soon Now is a copy of the skeleton user application which binds to the hijack menu, just so people have something to start with. I think Mark documents that on his site too, but I can't remember. It's documented in the source code itself but who ever reads comments anyway.
