Since most people don't change teams every day, we might add:
"All credits you have achieved for POEM@home before joining the Charity-Team, will remain with your old team (and with your own account of course). During the Benefit-Crunching all additional credit for POEM@home will be added to the Charity-Team totals (and to your own account of course)."
Yes, I know, this is not about personal credits, but people
do care about it, you know.

Especially our friends from SETI.USA do...

... sorry, couldn't resist.
