SilverBoy,
there was once a script called "Nuke2vb" which combined vb and phpnuke. Since then it has been altered a lot! and most of the phpnuke stuff was taken out, cause of the poor html coding that was done in the early stages of phpnuke. vbPortal was born, to use what phpnuke had and what vb offered, and now in the process of being completed is vBPortal v3.0 which is nuke2vb+advanced. It used phpnuke 5 and is looking really good.
Since phpnuke has such a strong group of followers and addons and hacks are always coming out, it was thought up to let vbportal use the same addons and hacks that were made for phpnuke. So you see here in a few weeks or months, vbPortal 3.0 will come out and will take advantages of phpnuke and vb. So don't count vbportal out
