Post away. I'm interested.
As far as promoting one's workshops on the forum in general, we've been fairly easygoing about this when it's been a case of a regular participant in the forums who announces the occasional workshop, like Cheryl Jacobs or Aggie, as long as it doesn't become abusive. The concern is about drive-by posters who just come to APUG to flog their workshop or forum or product or magazine or whatever and don't contribute anything else, either as regular participants or as sponsors. As I see it, you've got nothing to worry about in this regard.
