At the moment, the yearly KDE conference Akademy is taking place in Milan. The yearly KDE e.V. meeting will be tomorrow.
KDE e.V. is a registered non-profit organization that represents the KDE Community in legal and financial matters.
For example the KDE e.V. is responsible for paying the servers that run our Phabricator/Bugzilla/Gitlab instances and all our web sites. KDE e.V. takes care of sponsoring developer sprints and contributor travel costs, too.
If you are a KDE contributor, consider to join the e.V. to get some vote about its direction.
If you want to join, just take a short look at this guide.
