vB4 Converting 3.x Trial Membership Days Left Hack for 4.0?

[محروم.كوم]

I'm referring to Jake's code here http://www.vbulletin.com/forum/showthread.php?t=184194 which I used to use before I upgrade to 4.0. I've PM'd him twice but no response even though it shows him online.

Where do I post to get help on this or help on converting 3.x code like this to 4.x since there are several such mods I need to update but the new 4.x code is greek to me, even though I am a programmer and handled 3.x code fine. __DEFINE_LIKE_SHARE__
