How do I add the module? We tried to add a previous module and couldn't figure out how to add it. Is there a place I can find a list of these modules? It seems to me that the answer to half my questions is add a module.

If you have subscribed to the OpenERP Enterprise service (or are testing with 3 users or less) then you do this via the APPS menu. If not, then you need to download the ZIP from the link I posted and copy it to your addons folder and update the modules list. http://help.openerp.com/question/40852/how-can-i-install-modull-in-openerp-7-without-internet/ The list of modules available is at apps.openerp.com
