A few weeks after its release, a brief overview of the support put in place by OpenERP for users and contributors.
The OpenERP installer for Windows is ready, as are the packages for Debian-type and RedHat Linux. You can also find the sources to compile your own version. Modules are in a dedicated section that has not yet evolved.
The page centralising community information is quite complete (IRC, forums, Development Centre, etc.). OpenERP uses Google Plus to communicate with partners, users, and contributors.
There is also a French section. Note that the AFPy (French-speaking Python Association) offers a dedicated mailing list.
On the technical side, a FAQ is available and finally, the indispensable source code of the various projects is on Launchpad.
