Hey John,
I really like the studiointeractive website, but got bored very quickly with the newsletter sign-up. There really wasn't enough information or insight into what I can expect to get from your newsletter. All the links seemed to work fine and it was easy enough to subscribe/unsubscribe to the newsletter. As a potential subscriber, I would want to know what separates your information from the thousands of other newsletters you can sign-up for without having to read the whole newsletter. I would think of maybe highlighting what will be featured in the next newsletter or providing a quick tip on the first page. I see in your latest newsletter the lead article is about Promoting your site for free. That is a very catchy article header and seeing something like that on the home page would definitely get my immediate attention. By highlighting the topics you will be discussing next, it can create a sense of curiosity and anticipation of maybe getting that one big tip they have been waiting for.
I really like the logo design and color scheme you've chosen.
