Online Colaboration / Whiteboard Tool - Hosting on my server
Does anyone know of any online collaboration / whiteboard tools I can host on my own server? I have looked at online services, but unfortunately my work firewall breaks/blocks the majority these online tools.
I just want to have a simple tool that allows me to email a link to other people in my team that are in other offices, this link will show them a simple space where we can collectively scribble notes to each other. We can then dial up a conference call number to discuss our progress and at the end of a meeting save the scribbled notes as a JPG to send out to everyone.
Does such a tool exist?
