Sometimes ago, I changed the rights for anonymous people (aka those who don't have an account on this wiki) that let them edit the wiki. But as Valérie told me, she wasn't aware of this change, and thus I guess others didn't notice this either.
The idea behind this modification was to make it easy for people to ask questions through the Flow boards (the new structured discussion feature). This wasn't a definitive decision, though, but more a "let's test this and see where it takes us". You can see the thread regarding this decision here
However, I agree that this change isn't a small change. For instance, it would mean that we don't know who is the person making change to a page.
So, what are your thoughts ? Do we keep this change, or do we revert back and allow only confirmed users to edit ?
Also, I could try to find an alternative, where anonymous can only write messages in the Flow discussions (but last time I checked, it was quite complicated...), but then I'd like to be sure that everybody agrees with this.
