CMS decision

In an effort to learn and to understand more about Content Management Systems and find one or two that I would like to continue using, I have decided to use TextPattern for a new client website I am designing (teddrums) and for my new business oriented website (halfofone). TextPattern utilizes a MySQL database, which is brand new territory for me. I've been looking into CMS's for a couple months trying to sort out the functionality, stability, workability, and usability. I've used TikiWiki for a previous client's website (Wicker Park Grace). So, onto more fun with new things.
