Don't know if you've been directed this way or not, but as an FYI--
Most of our WAHMs take advantage of the Business Signature & Advertising
deal (the first one at that link) so they can link to their venture in their signature, have a pic of it under their username, and place a dedicated ad thread in the WAHM Market. There are other perks too described at the link. I'm just posting what I can remember off the top of my head.
Until then, if you go to your UserCP (top left) and go to Edit Your Details
, down a ways under Optional Information is Home Page URL. You are allowed to put your website in that slot for free and allow members to find it on their own.
