. Please let me know what what information you need
We are really interested in your product thus we have the following questions:
1. Is there any limitation to the user numbers?
2. Can we add/customize fields regarding the user profile information (example: job title, year of employment, etc)
3. Do we have the option to set different permission rights for users?
4. Can we have more than one moderator? If yes, is it possible that each moderator is assigned to specific groups so that he can only see information in the groups he is assigned to?
