It's insulting to expect people to do work before an agreed-upon compensation rate.
Also, "Western team scheme have many disadvantages, such as too many implementation links, difficult supervision, weak participation and slow motivation, etc. " Can you please explain this in detail? Why is Western team being lumped in with Ambassadors?--We are not paid by community funds. We work under the restrictions and limitations placed upon us by core team. I will assume core team thinks western team has: "difficult supervision, weak participation and slow motivation." Where is this impression coming from?
