There were some slight problems at first (down to me using Windows hosting rather than Linux) but Michael offered a fantastic level of support, both on his blog and through email. For 4 dollars (£2.50) this saves so much time. Cannot recommend enough!!
We still don't have this option since we are working on version 3.0 where it will be removed.
Until then, we offered our support to each client who wanted to remove ""powered by" message.
So, it's not really true that "there are no easy options to remove", it's really simple, you just have to ask.
