Where can i get mods for vb5
 

hello guys
im looking for following mods of vb5 that are working:

Seo
Refferial System
Hide Content till get x posts
Ranking System

is there any other place where i can find it or request someone to write?

You might want to be more explicit. vB5 has SEO friendly URLs, so how do you want them to be different than the default ones? And what is a ranking system? and referral system? and hide content? How about a link to these mods you want?

I'm not sure where else you would get any besides what's already here.

The simple fact is almost no one writes them.
vBulletin 5 is (for various reasons) very unpopular with anyone likely to actually write any - so few actually exist.

Or they write them for their own forums and don't publish them or give them away, myself included. I have helped several people get started writing mods for vb5. Some of the mods ended up being pretty complicated and had many hours of development in them. These mods are what makes the forums unique from all the others.

okay i need this one for vb5

and some Refferial System like invite "x" friends that will post or buy "y" amount to get free 30 days paid subscription to "z" forum

Your best bet is to create a thread in the "Paid services" section. But even then... there are probably close to zero developers who can make such thing for vBulletin 5.

i think the easiest way is restarting with vb4 as long as there is not much content/users in your forum, because a downgrade is afaik impossible.

[edit] when the addons you need are availiable for vb5 you can switch back again.
