[tg] Update for Weds 3/25

[Judy Anderson <yduJ cs stanford edu>]

Summarizing for those not on discord:

There has been a change. There is Covid in Alex's house (not Alex, and not 
anybody who would dance C3). David volunteered, and we have scraped 
together 8 people, and rides for those who need them, to attend C3A at 
David's.

I have some C3A material on my laptop.

Neither Alex nor Della will be coming. I changed the location on the 
spreadsheet to David's, but I did not change their entries to "no". (I 
suppose in some fantasy world Della could teleport after her meeting.)
