to be adopted. We should increase the limit and increase it now. 20MB is simply too big and too risky, sometimes we need compromise and push things forward. I agree with any solution lower than 10MB in its first two years. On Mon, Jun 1, 2015 at 7:02 PM, Chun Wang 1240...@gmail.com wrote: On Mon, Jun 1
