The only host I found so far to support mysql triggers on shared packages is at http://www.placehost.net. I hope more will come. This is probably because hosting providers wait for plesk or cpanel to support such versions of PHP/MySql and those two are moving slower than anything else. PHP 5.2.9 came out recently and a lot of bugs were fixed yet nor cpanel or plesk supports this version. Mysql releases 5.4 soon so triggers will no longer need the super user privilege to be added, but, as always, how much time will the control panels need to support it?

I'm impressed! You've maanged the almost impossible.
