A coding suggestion: Replace the two deprecated iif functions (used in post_thanks.php) with ternary conditional operators.

It's also a very, very small speed optimization (less function calls).

There are also some old queries in the functions_post_thanks.php code (replace them with read, write, first, ... queries).
