Contact
Er, for the organizers, just email us —- you can find our contact details from our pages on the list of alum.
—- Joanna, Rocio, Bettina
For contacting everyone else —- There is a tag contact-info, so you can see which alum pages include contact info (even if it's just a link to an external web page.)
There is also a tag self-edited which shows which pages people have updated themselves.
