Minor hurdle with install but I'm tech savvy (but Joomla newb) and forums were a great source of help. After that my problems began - spent a day going round in circles trying to work out so called profiles etc.
Crikey!!! All I want is a search & list on the front-end for goodness sake. With links to email perhaps.
The main area I see as a weaknesses is in the documentation. Sure I could get help but I'm developing this as an intra-net and access to external people is damn difficult in a 'locked down' managed environment.
For the time being I'll use the basic contacts and come back to this "maybe" when it matures more.
