@momofsenior, as previously announced, we have invited experts and authors to participate in forum initiatives like AMAs or school chat parties. When announcing such initiatives I put up a post introducing the expert (and include a link back to their website/YouTube channel/business).
The ToS have not changed. It is not allowed to use the CC Forums to promote your business or solicit your services. These experts/authors are not exempt from these rules, so please flag whenever you see violations. Thanks!
