My b2evolution Version: Not Entered

Hey,

i need answers from the veterans of this thing.
yes i know to read this and that but i have specific questions and i know u guys have the direct answers
what are the real possibilities of this thing.
I have a static html website and i want to convert it to a cms of some sort that makes it easy for me to customize.
The reason i'm going cms is to have controlled user management..if u know wat i mean.
but, i would like all my existing modules to remain the same.
i want to integrate my coppermine gallery
my phpbb forum
my flashchat, amongst other things
now so far, is any of this possible?

Wayne
