Is there a central place that has all the various signs, posters, etc. that are made for the OLPC project? If not I think there are many benefits to having a single place, or a single group of places that handles the production of things like this. The benefits I can think of are:
--People won't have to recreate the work of others.
--Volume discounts and limited set-up fees.
--Peoplw would be more likely to use signs that would help the profitability of fund raisers if they were aware of their availability (if we post it as a major wiki section on the left hand side of the home page)
If there is a way to procure this kind of stuff then perhaps it should be more visible or more easily found?
