Alpha and Beta testing of R versions

Maybe we (the R-foundation) should give serious thoughts to
offer prizes for valid bug reports during alpha and beta
testing.  These could include
- Reduced fee for 'useR' and 'DSC' conferences
- being listed as helpful person in R's 'THANKS' file
 {but that may not entice those who are already listed},
 or even in the NEWS of the new relase 
 or on the "Hall of fame of R beta testers"
