Ummm, I was one of those 5 million. You raised some questions. Will the
classic SETI users be transported over to BOINC? If so, will our stats be
kept current? If so, what about my 5000+ completed wu's, can they be added
to the BOINC effort? (Don't get me wrong, the science comes first, but the
numbers are nice also. :)

The credit system in boinc is farrr different than it is with classic 
SETI@Home.  In classic S@H, you're given one point per workunit, period.

With Boinc, things are a bit more complicated.  The boinc core client 
(which controls applications like seti@home and astropulse) detects how 
fast your computer is, then how long it takes the application 
(SETI@home) to complete a workunit and claims a certain amount of credit 
based upon the two variables.  After a few results come in, the server 
then grants a certain amount of credit based upon various results.

Now, credit ranking is based on one of two things, depending on where 
you look.  It's based on Recent Average Credit (RAC) or total credit.  
Recent Average Credit essentially tells you how much work your computer 
has been doing lately... it's based on a sliding scale with results 
returned today having much more weight than results returned a while 
ago.

I prefer looking at RAC over Total Credit.  Most people play the rank 
game with RAC anyway as it's easier to change quickly.  The current top 
team, considered #1 by most (we just passed the French and German 
teams), has a RAC of roughly 500 points more than the French team, but 
we have roughly half the total credit.  :-)

Anyway... boinc is currently beta.  It's in a late beta stage, I 
wouldn't be surprised to see it released in a month.  Give it a shot if 
you have the time.  Stop by #boinc on irc.freenode.net, too.

Happy crunching...
