Mr J: No problems, if I could pay you guys to help me test, I would, but since I can't, I'm pretty much happy with any response at all haha.
Drewbee: The database connection is encapsulated in an object at this point. It's the first object to be loaded by the system, the handler is stored in a static property, and no, at this point there is no major abstraction going on, it requires MySQL. I have considered providing an abstraction, however I torpedoed that aspect of the project earlier on in favour of getting other things done - I figured if the interest actually goes anywhere in this as a public domain resource, I can reconsider and reopen that possibility at a later time.
There is rudimentary template handling built in at this point, to handle the internal mails (verification, forgotten password, etc) and built-in menus ('you are/aren't logged in' type stuff). I want Tuatara to be highly adaptable and functional, but it is also meant to be transparent as much as possible - so while the current testing package is basically a reproduction of my demo web site for it (to make testing easier as you don't have to build it around anything, it already is), it will eventually be stripped down to just the library, installation routine, and relatively un-styled sample pages to provide the end user with a kind of outline of how to integrate it into their existing site.
My long term goal for this project is to create some kind of plug-in framework for it so that anybody using it as their authentication/access control layer can drop in modules for it, like a blog, or a forum, etc that will use a standardized authentication across the entire site - something so that a community can expand beyond a simple this or that but not both interface. My short term goal is to actually get up the gusto to finish docblocking the whole damn thing and generate an API, then strip out any extraneous code and make it as a non-bloated as possible.
I'll email all you all with the download and information regarding testing - thanks again to everybody for their help.
