Buying 3 vBulletin licenses* but first i have questions
 

I'm going to buy 3 licenses in the next days* but i have a few questions

1) Let's say i am already using a nulled version of vBulletin on the 3 websites. Am i allowed to keep my nulled version if i buy a legal licenses or will i have to use vBulletin's official files ? (which is a lot more trouble considering i would have to rebuild everything from scratch)

2) If i understand correctly* to get the feature of member's blogs (each members are allowed to post blogs in their profile) i have to order the vBulletin Publishing Suite ?

3) Three licenses are sold at 555$US. That's 185$ each instead of 195$ each* but let's say i want to replace one of the 3 licenses by a Publishing Suite* is it possible to buy two licenses at 185$ each and a Publishing Suite license for 235$ ?

4) Let's say one of my forum is using a old version of vBulletin. Since this forum would have a lot of ennemies* i would have obviously removed the "powered by vbulletin" notice so the ennemies of the forum aren't able to google a sql injection code in a few seconds and hack my forum.... Can i get in trouble for doing that?
It was VERY hard for us to find all the money to buy 3 legal licenses and we had to ask our members to help us. If we did it* it's only because we don't want to start over from scratch. But if i am forced to put a copyright notice that could lead to the hacking of my forum i'm going to have to upgrade* and that would mean losing the custom mods i spent countless nights to make* losing my custom template* everything. That's days and days of work... If we're forced to start over it would be cheaper to look for a free alternative like phpBB or SMF....

We really can't afford to spend one more dollar on this and of course don't want our forum to get hacked* neither do we want to start over because we need to upgrade..... Like i said it was very hard for us to raise this money* our members are very poor and this is a non-profit website (we already lose money paying server costs)

Is there a solution for peoples in my situation ?


Thanks
