hi,
please move this topic to correct section if i am posting in wrong section.
#1
i am currently using phpbb but now i want to use Vb, before buying VB i have some questions in my mind because i am new to vb.
first of all i need some mods/plugIns and i want to know if they are available in vb or not, if they are available then are these already installed/bulleting?

1 = quick reply
2 = View PM's of all users in CP. (Spy PM in phpbb)
3 = view ip with every post for admins
4 = welcome PM to new users
5 = Post count changer / increaser / modifier
6 = Fonts
7 = reputation or thanks functions
8- send PM to all users at once
9 = A Mod which can Add "Resolved" or something similar to this in Thread Title.
like "Topic Prefix Tags" Mod
10 = a mod/plugIn Automatically moves users into a special group when they are banned. This allows you to visually indicate that a user has been
banned through the use of group attributes, such as a custom rank
image. Users will be removed from the group when they are manually
unbanned or when their temporary ban has ended.
11 = warn user by x warning, automatic ban on 100%

are these PlugIns available in vb, if yes, then which of these are bulletin?
are these free?

#2

if yes, then any tutorial for this?

#3

why vb is better and why should i move to vb?

#4

will i get all the help and support needed for free if i buy vb?
