Aw, shucks. Genius?? Not really.
When I was at a university in hte States, I ran out of tuition money during my last semester, and I actually prevailed on half my professors to let me continue in their courses in an “auditor” status (this included a 10 hour a week Russian language course, too). I always took that as a guide and now whenever I am in the position to say, I let anyone who wants to audit my classes do so.
I think most professors in Taiwan would be pretty open to this (maybe you should try to pick ones that aren’t 80 years old, though!) because I think most are intrigued to see a foreigner who bothers to learn to read that stuff in the first place. Most teachers are going to be favorably impressed by academic motivation wherever they find it, so if a teacher doesn’t let you audit (might be for institutional reasons too) be sure to ask if s/he could send you to another place that might work out.
Hey, you might try some of the “extension education” classes at the various universities, too. I’ve never paid too much attention to their literary-type things but I would suppose they might have some sessions. Also, why not try posting to (I’ll probably screw up the name of the group here) tw.bbs.language.chinese or whatever it is? That’s a group of folks who are always going on about this character and that piece of writing, and seems like they might have some suggestions for you too.
