So today would be the big day for launching the Joomla extension.
But I sense some radio silence. It would be appropriate to let the customers know when there's been a delay or a new release date.
You've got a fine product. You don't want to risk loosing the momentum of an anxious and overall favorable state-of-mind of your clients.
Word of mouth is a powerfull thing. I intend to give a small presentation on your product early February on a conference I plan to attend. It would be nice to show the Joomla extension there. It could generate some revenue for you.
With kind regards
