Important Notes

• When development, turn on display_errors in php.ini. Turn on Debug Mode in XOOPS Admin page, so that you know what is happening.
• If using CVS/SVN to do version control, I think it is preferrable to NOT using multiple themes/templates and edit the default files directly, so that the changes are keep at the file level instead of inside the database, which is much easier to do tracking.
