All - last week's call for compound designs to the CoV-2 main protease (https://covid.postera.ai/covid)
elicited an astonishing response...  (I confess I was quite taken aback.)

I just realised I should let this BB know the second call for designs is now open.  Deadline is tomorrow 23:59 PST (April 2nd).  (Apologies for those that weren't following on twitter.)

Two things: 

Happy designing!
