Those who register for the business directory should not be considered volunteers. The purpose of the business directory is for free software businesses to publicize themselves and help free software users find an appropriate business for their needs. The term volunteer should therefore not be used in this directory.
Secondly, I don't think it is necessary to distinguish between individuals and organisations in the business directory. Even an individual businessman usually has a name for his business or consultancy.
The listing of entries in the business directory needs lot more information than the sample application shows. Please remember that unlike the volunteer directory which will usually need to be accessed by people at FSF-India (who have management access to the zope database and hence can see all the fields) the business directory is primarily meant for viewing by the general public. Thus no fields should be considered private and all information entered by a registered business must be displayed at the time of listing.
Please give some further thought to my inputs in the earlier mail based on our experience with the FSUG-Kochi business directory.
