i just got another hit from someone searching for arabic courses in philadelphia. i've been getting these occasionally for the past few weeks. i'm not sure whether it's the same person doing a periodic search, or if there's just a bunch of people looking for arabic course around here.
in any case, whoever you are:
while i do have information about studying arabic locally, you probably won't be able to get it all from this site. a better bet is to email me using the "harass me" button on the right. i'd be happy to help.
