Do the points cost the same for both sites? If so maybe you could somehow link the points system so they are like universal. like the euros. they are good in all simply comunities. especially considering a lot of people i notice have more than one program. getting 20 simply points use 10 on each site.. or 9 and 11 in case your short one. although its prolly a lot more difficult to enact than i think. or else you would have done that already.
