I use Bluebird to host 3 wikis.
They provided great support importing the wikis from the previous hosts, and they always help when I have got myself into trouble by messing with things I don't know enough about. Very responsive, friendly service!
Company Response: Thank you Tina for your review! We always try to be as friendly as possible and give our best. regards Bluebird
