Hi,
We are currently quite busy with the development of HikaShop 3.
The support of Komento is in our TODO list but not with a big priority ; HikaShop provide a rate/comment system, so there is no feature lack even if the Komento integration could be an interesting improvement.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
