Two things...first, there's a typo in your INSERT IGNORE INTO explanation. I think you meant:

Assuming username is a primary key or unique key, this query will insert a new record if the username Pandemikk does not exist or do nothing (no database error) if it does.

And second, when you say query_write, you're still typing query_read in your examples. Is this correct?

And I'm assuming this article is valid for both vB3 and vB4?

I'm still learning PHP, much less vB programming, but this helps a lot! Thanks!
