Thank you refertech. I'm not
that good of a hacker yet, but I try to help where I can.

Yes, it is safe to upgrade to 2.3.0, but when you run the vB upgrade script it will delete the myvbindex templates that have not been customized. That's really not a big deal though as you can just upload the myvb_install file to your admin cp again and go to
http://yoursite.com/forum/admin/myvb_install.php?step=2. That will install only the templates for you, and any that were customized will remain the same. As long as you do that you shouldn't have any problems, but if for some reason you do let me know.
