On the download page you will see it states you can contact me directly at this website, there is and never has been a fee for this
However, technical help is not allowed directly by the Joomla extensions directory. I can assure you there is no three day time-out clause in this module.
Anyway, I'm very much a non technical person but installed this without fuss and not only does it work well but is sooo..... easy to configure. You can change which flags are displayed and the sizes too. It is also compact and doesn't take up much room.
I must also say that the support I received from Edvard, (this was needed because a lot of the content in my pages was not fully valid and was actually nothing to do with GTranslate) was superb.
