gpc10347 - Where are you seeing it work on my site? I still can't get it to work, so maybe it is your imagination.
Dr. Bantham -
First of all, have you tried the categories? That might be able to do what you want. If not:
WARNING: None of this has been tested, so don't try it on your live website.
I guess the simplest way to do this would be to to copy and rename quotes.php, admincp/quoteadmin.php, modcp/quotemod.php, and includes/functions_quoteit.php. Edit the new files and replace all mentions of any of those file names with the names you gave to the new copies.
Next, duplicate all the QuoteIt! database tables (quotes, quoteratings, guestquoteratings, and quotecategories) and rename them. Edit the files you created in the previous step and replace all references to the old tables with references to the renamed ones.
Your new quotes database would share settings, templates, and permissions with the "real" installation, and quotes in the new database won't be available for things like the bbcodes, but it should basically work.
