in every table that is created by phpMyFAQ? It wouldn't harm if the table already existed, but it would help if something happened to the database, and the db was wiped, for instance.
if the DB was wiped, you need to reinstall phpMyFAQ because you cannot log in to import your backup. I added the "IF TABLE EXISTS" in the installer if not all tables are broken.
Why did I asked this? Because I usually have to transfer the FAQ from one place to another, and I wanted to make this a smooth process. Re-installing everything would make me loose all the changes I made on some files. If the tables were created in the script, I could just copy the files, and restore using phpmyadmin for instance. The only thing I do now is use phpmyadmin to save the tables, making the backup feature useless
