I keep a bookmark for this forum and visit often, usually keeping my mouth shut because I have more to learn than contribute.
Most support forums would have something like a PJRC logo in the upper-left corner that takes you to the main site. Here it just takes you to the "root" page of the forum.
I hunted around and found a link buried at the bottom to PJRC Electronic Projects, your blog, and that had a link to your products page.
My suggestion is that you make it easier for current and prospective customers to find the other content and products. Once you get to this forum, it's like a walled garden.
