As you all know that PHPBB3 is one of the best open source forum board available on Internet presently. Though its functionality does not match other paid products like Vbulletin, IP Board and Xenforo but still it have enough functions to act as a decent forum. Not only this, PHPBB3 is much light on your server as compared to Vbulletin. Vbulletin is notorious in regard to overloading of your server and for this particular we had shifted our forum from Vbulletin to PHPBB3.
