To be honest, I had doubts about all these "free" services to begin with, especially ones like Zetaboards and Proboards.
They tend to provide a far inferior service to what you could just get by just installing the software yourself, and they usually make it difficult, if not impossible, to switch to anything else.
And neither is it in their interest to provide you an easy way out. I think anything they or Tapatalk push out will inevitably be sub-par and frankly awful. But, we will have to wait and see.
