[cross-post - please reply only on one of the mailinglists]
A month after the first call for testing the updated wiki, here is another one ;-)
Compared to the "old" test wiki , there were a few changes: - the test wiki is now running on the final VMs that will also be used for the production wiki - login is now done with the Auth_remoteuser extension (which means we can continue to use the "nice" login form) - the test wiki is now based on a (nearly) up-to-date snapshot of the english wiki - several changes "under the hood", including automated setup of the VMs and the wikis with salt, some extension updates, config tuning etc. - oh, and the wiki VMs are already running openSUSE Leap 42.3 :-)
That all said - the test wiki is waiting for you at https://en-test.opensuse.org/
Please check if everything still works, play with it, test the new features, ...! It is a test instance, so nobody will complain if you do test edits that don't make sense content-wise
At the same time, remember that it is a test instance, so any changes you do will be lost when I re-import the database dump for whatever reason.
If you notice any issues, please report them - either in one of the mailinglists (opensuse-wiki preferred) or send a mail to firstname.lastname@example.org
If nothing terrible happens, I plan to update en.opensuse.org next week.
If you enjoyed testing the new wiki, please also take some time to go to our current wiki (en.opensuse.org or $LANG.opensuse.org) - there are lots of pages that need an update ;-)
And finally - thanks to everybody who helped me to get everything in shape!
 See https://en-test.opensuse.org/Main_Page for the list of changes compared to the current production wikis. It's probably more impressive than the list in this mail ;-)
