BarCamp - How to Run Your Own/Schedule and the wall

Even if you have many rooms as we had, limit the tracks to 4 rooms so the attendance does not suffer.
Make sure you have at least 8 rooms for the event so sessions will be smaller and more discussion (many to many conversations) take place as opposed to one to many lectures. 4 rooms is not enough.
Make sure there is plenty of gathering room in front of your wall, people will want to gather round.
Don't put the wall in one of the session rooms, People will want to look at it mid-session sometimes.

The Event Slots

There are different slot sizes you can do, 25 minute slots seems to be about right
Ensure you give at least a 5 minute break in between sessions

5x3 index cards on a whiteboard or physical wall works best
We used masking tape to form an actual grid
Put breaks and lunch in as session sized slots - and put cards in that say Lunch or Break
- Don't just write on the tape in between 2 sessions "lunch" people won't see it
Post it notes tend to fall off in my experience, I prefer index cards with blutack or magnetic whiteboard pins
