Hi,
I just want to add that iFinity has been acquired by DNN, as stated on their website : http://www.ifinity.com.au/
So the full features of this module should be implemented and available on DNN pretty soon (and I'm not sure the module will still be supported).
The only thing is they might keep some of those features for the commercial part (Evoq).
Best Regards,
Stéphane
