I've found their forum it about the only way to contact them at the moment.

They respond to PMs and to threads.
And yes the critical ticket I raised to them a couple of weeks ago is still open. The solution was discussed on the forum.
Was greatly unimpressed with the UK2 debacle of the last couple of weeks. cPanel upgraded all PHP/MySQL with zero notice and put my shop out of action for a week while we rescued the database, decrypted it and upgraded it and the cart from 4.0 to 4.1. Would have been a lot easier if, like the current announcement for UK1 and UK3 they had warned me in advance.
I think Adam is finding that being a dad to Jessica is taking a lot more time and as such iWeb is taking a bit of a back seat. Willie is picking up the slack, but is not the Unix guru so can't carry everything.
Which server are / were you on?
