I think the whole process of whitelisting should be reorganized!
It's not very fair to add projects "suddenly" and then there are no new WUs to work on. It also reduces the income on all other projects.
Maybe there should be some mechanism that you can only get GRCs from a project if there are more than 500 active users?
The other thing is an insufficient amount of WUs with hight Credit, like it was on drugdiscovery@home with the CUDA WUs. Well I was one of the lucky ones that got some WUs and I was suddenly on top of the list, but that was also not fair. Maybe there should be some rules for the projects to avoid such things.
I know it's complicated and there are a lot of intelligent people thinking about this and we/they will find a solution.
