I'm looking to build an Interactive Collaborative Database with a Spreadsheet styled front-end.
The system allows multiple users (<10 per account) to update data in real-time, simultaneously. Changes made by one user should update in real-time for that user's designated "group".
We use ppSD2 to manage our users - site needs to interact accordingly.
Serious developers only, please. I don't want middle men or people looking to sub-contract the project out to someone else.
