A modular collaborative panel system intended for use on walls, frames and stands is disclosed. The system uses dry erase boards, chalk or black boards, or other panels having at least one writing surface. The panels have notches or cut-outs on each side so the panels can be mounted to a wall or a frame using pegs. The system combines panels in rows or columns, or both, to form a large, modular system for use at meetings, gatherings or other assemblies. The system allows a large number of users to contribute to a presentation, and also allows users to view the presentation.
