What does the company do well? They have a few themes that look nice if you want a canned theme website.
What does the company not do well? They have horrible customer service and aren't capable of answering even the simplest of technical questions. They also hold your site hostage and will not allow you to move to another CMS or hosting company.
What do you wish you had known about the company before using? I wish I would have known that their service was so horrible and that they don't care about their customers.
