OK so I want to change however Can I transfer all my members and posts ? Is their a way.
You would need to ask at SMF's site to see if their merge script supports Mybb.
can anyone give me a quick answer.
We wont give you support on that here...
Since you dont want to do the work your self,
here.
It seems they dont have one for Mybb 1.6
A) Why would you want to do that?
B) Blake already gave you the answer.
SMF has better designs layout. Is so hard to find good designs for mybb.
Then you're clearly not looking very hard at all. You've not found anything you like on any of these many theme sites??

Either way, we're obviously not going to help you convert to SMF.
