The alpha release of ByteHoard/e is oh so nearly ready; all that is left is pretty much one function, the "add user" function, and possibly registration if I think it's necessary (it probably is).
Recent changes have included the whole admin interface being added (which is also all AJAX code; I have a feeling I may regret this, but we'll see), the addition of a user preferences page, which so far only lets you change your password, full name and so on, and a new themeing and UI redesign so that the whole thing is a lot easier to look at and use.
Screenshots of the latest version are below.
