In his blog here:
If you are already signed up to attend community day, then you just need to add your name to this wiki page:
I went there and didn't see any instructions for adding my name to each of the four sessions.
Do I just edit the child page for each session and add my name at the bottom?
If not, what to do ?????????
I don't want to get shut out of these sessions, so please advise at your earliest convenience !
