Yesterday we rolled out an upgrade to ListPages. This broke some pages, sorry about that. We tried to do too much in one go. Things should be working better today and we've learned lessons that we'll apply next time. Meanwhile, a new documentation page is now ready. You can use this thread to report errors in that documentation or other problems you are still finding with the new ListPages.
For the next three-four days I'll be offline, taking a few days off with my family. Michal will be replacing me for these days, reading this blog and answering questions. Thanks to everyone for their patience and help in making Wikidot something special!
