Hey, sorry to clutter the forum with this thread, but I can't find the form to fill out for instructors on the site. I could find it on the old site, but not the new one.
I'm sorry, I've found the answer. Searching this time yielded results right away. Last time I tried (couple of weeks ago) I didn't find anything.
In case anyone else has this question, just search 'instructors' and then click on wikis.
