Hosting is kindly offered by the Titanpad folks.
Access is restricted by default, as that is a rule of titanpad sub-domain hosting; for non-restricted public access you can use http://titanpad.com directly.
to create a new pad you need to login using a shared account available to all DDs
account data are stored on /home/debian/misc/titanpad-password on master.debian.org
- once you've created a new pad, just share its URL with collaborators
note that all new pads are secured by default, so only people with an account will be able to access them;
to enable public collaborative editing go in your pad and choose Security > Pad Access > Public
Note: the shared account is mainly meant to create public pads. For private collaborative editing you cannot use the shared account at the same time from different computers; titanpad notices that and disconnects all but one client. For private collaborative editing you'll need to ask the admins to create individual accounts (they will probably ask you in turn to volunteer as an admin to create the accounts :-P).
The current admins of TitanpadDebianNet are:
feel free to contact them for problems (or to volunteer as another admin!)
