one possibility, rather than trying to rewrite things people have
already discussed, is to link to certain threads that explain things
clearly, be they bits about marker generation, x/y/z position,
lighting conditions, whatever. i think it's unlikely that new users
will necessarily know to look there, but it could be a good place to
which to point them when faced with questions that have already been
answered.
if we go that route, though, it would be nice to separate those linked
threads from external links. probably best to create a new page, and
put them there. call them "sticky threads"?
rez, if you want to create that page and dig thru the archives to
nominate some gems for inclusion, by all means, go to it!
thanks for helping out!
