Thanks for asking Carol Ann,
It's absolutely fine - and do feel free to put anything you want on your own page (as long as it is polite!:))
We just have to watch for members placing ads and advertorial in our public areas, as that is unfair to other members and to our advertisers.
Also, if you want to talk about your teaching or share advice or experiences in our forums or blogs, we would all love that! Just not commercial products or links in the middle of posts to commercial sites - stuff like that.
