It combines a project manager, file manager, task manager, calendar and forum all into one to form one of the best project management tools available.
I understand it has been completely rebuilt to work seemlessly with J1.5 - and it certainly does. Any review that does not refer to v2.0 is no longer relevant.
As for the help and documentation - there are very clear links to all the documentation, there is a demo site with backend access, getting started videos and a forum. Not sure what else they could provide.
What's more, this is a FREE component. I have upgraded to the File Manager Pro which I paid a small fee for but it adds some great functionality. BUT, the all "off the shelf" free file manage included in the package is more than adequate for most needs.
Simply mindblowing bit of work by Tobias and the team. Well done and thank you for making my life easy!! :-)
