When asked by my MD to reproduce our joomla site on cd i groaned and expected a difficult time getting it to work, joomlas2go proved to be a lifesaver for me.
I donated to become a premium member, a mere 33 euros. And it was well worth it for me.
It isnt so much the package that stood out for me however (although it works fine) but the support.
I had a problem initially, and logged a support ticket. Within an hour Gabriel had responded and helped me sort things out.
If your like me, IT literate, but not heavily technical and want to build demo cds etc based on Joomla, i can wholeheartedly recommend this product.
