From what I remember Honda Karma was taken over by a new owner, cant remember the company, & from that point forward the forum went downhill till the company that had taken it over got into difficulty & vanished taking the forum with it.
Its sad that facebook & other platforms are slowly killing forums off as facebook really isn't anywhere near as effective a resource as a forum when it comes to searching for information.
Its also really nice to have a UK based honda forum. Just a shame its not a little more active on here.
