forum now Is there any Mod/Hack that helps me to earn money from my private forum.

If I understand correctly....

You can use the existing paid subcriptions system to take payments from people (via paypal etc etc), once paid the system can automatically place them into your VIP group and therefore access the private forum

where can i get existing paid subcriptions Mod/Hack

It isn't a mod it is part of the default vBulletin feature list.

Have a look at:

Admin CP -> Paid Subscriptions

This is an already installed feature of Vbulletin which will help you make money from yoru members if they choose to sign up

could you plz tell me Mod name plz plz plz

Two people have already told you, it's not a mod. Use the subscription feature of vB.

There is not need for a mod.

From the manual - Paid Subscriptions

Or you can use this https://vborg.vbsupport.ru/showthread.php?t=201284

However I'm having problems with the V.I.P. section to read to it. And the creator of the mod, is not providing much support... Kinda getting annoyed about it, because I've been looking and looking trying and trying to get it set up correct...
