which forum software is good:
I think vBulletin software is good as compare to other.
but Xenforo is also better.
VBulletin is $195 and Xenforo is $140.
Now a days, XenForo is performing good I would say.
PHPBB and vBulleting both are good forum software to develop forums websites.
According to me XenForo is the best forum software.
