Laura,

Thanks for summarizing the choices here. Was recommended on the TF call 
today to actually turn this into a survey to be used to gage wider 
"temperature taking" from within the TF. Mike(tm) Smith will coordinate that 
survey, but it was also suggested to sit on it a bit, as CSUN will be a huge 
distraction over the next week or so for many.

Perhaps ping Mike directly to ensure all goes well? (wording, etc.)

Cheers!
