You can see for yourself,how the work is going and give suggestions:
go to demo.vbulletin.com/index.php
When the pop-up dialogue box appears,give the following info
and then login to the board using
select language,bangla, from the footer,and see.
The work is almost half done,and I have to Do it within 12 hours as after that the demo board will expire,but I am quite confident I can manage it.
