1. Export PDF feature is not working. When I selected this option, an inline-window opens with a graphic that makes one think something is happening (animated GIF FTW!). After a few seconds the window closes. No file download window is offered. No download link appears. No PDF. FAIL!
2. Email link not working properly. I received an email of my sitemap (a simple unordered list in text format) with an SQL statement in the email. Definitely a security issue.
3. Site map not saved when save clicked. After spending half an hour building a site map for one of the websites I’ve built at work, it is really disappointing to not have my work available.

I wouldn’t want to rely on this service at this point. I’ll give them the benefit of the doubt for now that these problems will be resolved and will check back in a week or two.
