First thing's first, Chameleon Submitter has nothing to do with building a TGP and updating it.
Like Spacemanspiff mentioned. You can ask your host to set up a cron job that calls the page
http://www.yourdomain?com/cgi-bin/tgp/cron.cgi once a day.
That cron job should look like this probably:
Code:
0 0 * * * /full/directory/path/to/cron.cgi --all
That would refresh your pages every day at midnight.
