Please note that a poll about the depoyment has just begun on dewiki:
https://de.wikipedia.org/wiki/Wikipedia:Umfragen/VisualEditor_Opt-in
At this time, 410 users on German Wikipedia are against the deployment of the Visual Editor and want everything to remain as is (opt-in for registered users only). Only 20 have spoken out in favour of VE as planned. 4 are in favour of making VE the standard editor for logged-in users as is. 28 have asked for a different way to activate it other than the edit button.
The German Wikipedia community asks the WMF to not deploy VE on Monday as planned for all users.
Regards, Jürgen.
