front-page news rotation policy?

[Sandra Loosemore]

Gerald, do we have a policy on when to rotate the News items on the main 
GCC web page to the "Older news" page?  Joseph asked me to post a patch 
for adding a news item for the proposed new C-SKY port, but the items 
that are there now seem somewhat bit-rotten (e.g., referring to last 
year's Cauldron in the future tense and no link for this year's event) 
independently of anything to do with C-SKY.  Of course I can fix that 
too (with a separate patch), given some hint about whether/how much 
pruning is considered appropriate.
