Welcome to the renewed WatSan.eu Community of Practice.
This website is still under construction, but once completed will improve usability of this Q&A forum significantly.
For now you can still reach the old news feeds via https://news.watsan.eu/
Also check out the cloud collaboration space on https://files.watsan.eu/ (use same login as this forum).
Edit: we are also working on an improved wiki here: https://wiki.watsan.eu/ (You need to be a member of the Editors group to log in and edit the wiki)
Edit: the chat currently still requires an external account on matrix.org, but we are looking in alternative options right now for a more integrated experience.
