I'm teetering on buying another license for my main site and moving over in the new year. I'm still considering my options, but I feel there's just something about xF and the community here that is different in a really positive way.
It may all change, mind you, once the commercial aspect of providing the software / support / services kicks in and people start making demands and the software grows, but since I know about the previous track record of the team here I think we're pretty much guaranteed a success and more good things to come.
I want to get back to basics and I think xF might just be the key to that.
