yeah, gotta agree. without the methodology, no one will use it. plus, if the users don't even have admin on their machine, good luck installing stuff and keeping it installed when the real IT department finds out.
go for the offline solution like a whiteboard. put it in a location where everyone has to pass at least once a day, or in a meeting room where everyone goes to update it together on a regular basis.
either way, make a point to use it and stick with it, but be flexible enough to make changes to the methodology if it isn't working.
It is now pitch dark. If you proceed, you will likely fall into a pit.
