Hack of the Hack:
This modification will change the style sets of users in their birthdays so you can design a custom style for your users to show in their birthdays (a fancier one for example)
Features:
* Their style set will be assigned to any style set you assigned in the day they have a birthday and it will return to their default style sets the day after.
* The birthday style will be overriden in the forums which have MANDATORY styles.
* Style set will be changed/reverted according to their OWN times (unlike the hack).
* You can set a style set with no banner advertisement or have some special offers etc when user has a birthday. (But be warned: a wise member can change their birthday everyday to have this style forever, so dont make something so tempting!)

* This modification is APART from my hack so they are not related or not depending eachother. You can use both together or use just one of them without installing the other.
Installation:
Edit global.php
PHP Code:
// figure out the chosen style settings
unset($codestyleid);
unset($style); // prevent some weird issues
Find:
BEFORE that add:
PHP Code:
// Logician Change Style in users' birthday hack
$today_birthday=substr($bbuserinfo[birthday],-5);
$today_of_user = vbdate("m-d",time());
if ($today_of_user==$today_birthday) {$bbuserinfo['styleid']=X;}
// Logician Change Style in users' birthday hack
Replace X with the style id you want to set.. That's it, enjoy..
