Ok, then that's what I'm confused about...I just added a user from a dropdown list, and I've never been asked to make up a password for any of the users because phpBB did all of that automatically I guess (and like i mentioned, up til now, that's the only context in which I messed with SQL or phpMyAdmin at all.)
I guess the next question is how do I add a user to that dropdown list that it gives me to choose a user from?
[EDIT] Ok, so I am a total moron. I found where to create a new user. Anyway, did that, updated the config file in question with the new info, yadda, yadda, yadda. Still getting this error message, though: "Cannot connect to the MySQL server. Please check your variables and re-upload the config.php file or try again later."
[ANOTHER EDIT] Arrrrg! On the FAQ for the directory script, I found this:
And TCH runs PHP Version 4.3.8. So that means that this is hopeless, correct?
