Found gConverter on Google. We wanted VBulletin converted to Kunena. The communication has always been good... short but professional and personal. The final job completed smoothly and we felt satisfied with the results.
On their website they write that even after payment, some possible unknown issues would still be addressed. However, there has been no response for several weeks after we reported a small issue (first reported August 22). We'll see where we will get with this. Otherwise the total experience would be 5 stars for sure.
