well, work backward through the installation txt file :-p if you cant find an edit, you probably put it somewhere else or never made it, in which case you should try using the template searching feature in your acp, and search for partial lines (not whole blocks) as whitespace varies widely from what i see people doing
TMS is the template modification system available here at vborg. basically allows you to manage template edits like plugins, allowing you to update vb without having to redo all of your now-expired templates.
i hope you change your mind in the future, especially after some of the addons are done

btw, there is a vbcommerce demo on the official vbcredits site if anyone hasnt seen it yet
