This is really a note of frustration not just at Artio but many of the other extension writers for Joomla.
Many seem to rely almost totally on forums to provide support and I really don't know if some know just how frustrating it is when trying to resolve a problem to have to hope that someone might respond to a posting. On occasion I have waited 6 months before getting a response, that was on a Google forum.
When an extension is free then one can only expect limited support, but if one has to pay, as I have done, for an extension then I really do expect to get a proper level of professional support.
I always check the FAQs before posting, though they always assume that there is no fault with the software.
So come on guys, show that you are different.
I should note that some of the extension writers have provided excellent and quick support.
