No, you're not breaking any rules. The whole purpose of the forum is to exchange ideas. We, the Mods, only get ratty when adverts appear although it's also much nicer when original content can be uploaded directly to forum posts rather than, say, be linking to one's blog. That way members here can follow a narrative in the thread without constantly diving off-site. Thanks for sharing.
P.S. Talking of getting ratty, the post that WAS immediately above mine was from a first time poster with SPAM links in the Signature. Guess what happened to it!
