Is the list of potential contenders available somewhere?

It would be of interest to me but I am afraid that too much bike-shedding 
might ensue. Complex numbers are extremely straightforward with multiple sets 
of equivalent perfectly internally consistent minimal interfaces; in such 
cases, personal preferences decide the interface, more or less. See N1589 for 
examples.

Are you volunteering/proposing to run the LIAW session? What is the standard 
procedure for running the LIAW session?
