Etiquette question

[gmcgath]

I'm preparing a video course on ExifTool for Udemy.com, and I'd like to know if it would be legitimate for me to post an announcement here with a link. I'm asking because I'm charging money for the course, so it would be a commercial announcement.
One of my existing courses discusses ExifTool, but only for its format identification capabilities. This one is much more detailed.

I have no problem with this.  Post away.
