First of all, I want to say I like Lulu. It provides good quality printed books, which seem to be at a perfectly reasonable price, to me. The process of creating a project, uploading a 'manuscript' and designing the cover is all pretty straightforward - usually. The books arrive quickly when ordered.
However, recently I have run into two different problems with the site. That in itself is not all that annoying, these things happen. The quality of the customer support, however, is getting beyond a joke.
