Peter is a genius and a gent in equal measure and you can always rely on him for a quick and helpful response.
I had a couple of issues that needed some support but Rafael was quick and courteous in helping me out. Would be good to see a sitemap plugin to help with search engines but I have faith that the team will continue to develop this.
I did have some issues initially with getting the email working since my host puts extra restrictions on SMTP mail but after commenting out the SMTP authentication all worked well. I'm glad I could get it all working as this extension is a joy to use.
