YaBB SE to SMF?

[ferdz]

You want me to pay $49/year? I think I'll be stupid then.

It doesn't cost $49 to go from YaBB SE to SMF. SMF is free and will always be free.

A Charter Membership costs $49 which gets you an advance beta. Since you don't find value in that, then you just have to wait until the public release like many other users.

I would recommend that you read this post. It will probably answer all of the questions you have.

SMF is free. Full Stop.
