looks good overall. you're keeping the same design elements and apply mouse over coloring where it needs to be done.
for a forum, i think you've done everything that needs to be done. the topic is a bit "dry" and could use some visual backdrop work to lighten it up a bit, watermarking and such comes to mind. also, if you have the option, i'd present a side skyscraper that highlights the "tip of the day" where you display the SEO message of the day, in teaser form with a "...more" button. Upon clicking more the reader has to log in or register.
other than that, solid forum, nice job!
