We're just happy you're using Sitefinity! One of the big goals with the Community-version is to get developers involved with the Sitefinity product & community. Towards that end, we're happy to have you aboard!
I know you've already contributed help towards our KB articles and bug reports. Your involvement is helping make Sitefinity better!
Someday you'll probably encounter a project that would benefit from some of the features found in the full-version of Sitefinity. When that day comes, I hope you'll keep us in mind! :)
Until then, go nuts! Please toss me an email (firstname.lastname@example.org) anytime you have a new community-based web site to show. We're very interested to see what the Sitefinity community is creating!
