No - I found out by asking a question with a video link and it is apparently against the rules. I wanted to know if the video was valid/a real advertisement or a spoof. The question was deleted because of the video link - I think they said it was "overly promotional." LOL HubPages seems to get carried away with that "overly promotional" theme. I had to pull some really good hyperlinks in my article about dog whispering because it contained 3 links to the same website - I was referencing specific recommendations from the psrofessional associations about training and now I have a dilemma - because someone I'm sure is going to read those statements in my hub and ask well, where are the specific references you are writing about?' They will have to search the websites I posted at the end of the hub because I elected to include them as references at the end about other topics I thought might be slightly more important on the sites.
