How do I make template/theme changes?

[kecklor]

I have searched, but cannot find general instructions for modifying themes and templates. I'd like to change the layout of the index page, for example, beyond the options given in the admin.

In some forums here there are references to photopostdev.com but that site appears to have gone away.

Can anyone point me in the right direction? Thanks in advance.

we have mod forums at the bottom you can ask modification questions for stuff that might fall outside support
