What you may not know is that you can add that affiliate info into any Married Dance link you create in your posts. To do so, simply add "?aff=36&campaign=tmb-forum" at the end of any Married Dance link you type. For instance, a link to the Magic Wand will started with "https://" followed by (1) the rest of the address if unaffiliated, or (2) this address if affiliated:
Moderators will do their best to add in the affiliate information, but it's a lot easier for the posters themselves to add it in. Overall, this is an excellent passive way to support TMB.
One final note--on the Married Dance site, if you click a link or navigate to a specific product, you will notice the affiliate code in the URL disappears. This is completely normal. Once on their site, the affiliate information is saved in a cookie rather than being in the URL itself.
