If your community is going to be highly specialized in some area, and you think you are going to need a good deal of custom coding, then vB 4.2.5 would likely be your best choice. However, if your needs would all be met with the functionality of vB 5, then that would probably be the route you would want to take.

So, if you could give us some idea what you have in mind for your communbity, we can offer better guidance.

Thanks Sir , our community indeed gonna be highly specialized . its a religious community representing shi'a islam . a discussion forum . i did some research & find out most of VB mods/plugins/products support VB 4.x . there is very little available for Vb 5.x .
i would like to seek your advice Mr Mark . you guys are highly qualified & posses much more knowledge about VB .

looking forward for your advice
