1. I've tried MyBB in the past and found it really great! I want to know WHY should I use XenForo when I can use MyBB. I mean, what's there in XF which is not there in MyBB?
2. I want to create a professional "paid" forum and want to know is there any inbuilt functionality in XenForo like integrating PayPal, Clickbank etc. to sell paid subscriptions? Is it possible that there would be section where the thread can be posted only after the poster pay a little fee? Like if someone starts a thread he's redirected to a payment page and after he makes the payment, his thread is posted, without having me do anything?
3. I really liked the "look" XenForo gives to a forum and like I said I want to create a "professional" forum and looks always matter. But can't it be done by purchasing a high class MyBB theme?
Don't get me wrong, but I am confused and wants to make a correct decision before starting a forum. I don't hesitate in investing the money, but why to pay when you can get something for free? So, my main question is why should I consider XenForo over MyBB?
