Thank you for your feedback. I'm curious to know how you tested it. Here is what I did:
- I picked a random task from my Homepage,
- I click "Edit",
- I have the visual editor.
I did it using my work account and also a brand new test account.
At the moment, your wiki has one single "edit" tab. By default, clicking on it loads the visual editor for new users. If they switch to the 2010 wikitext editor when the edit and save from this editor, then the Edit tab will open the wikitext editor until the user switches back to the visual editor.
The help panel, shown when people work on suggested edits, encourage users to switch back to the visual editor.
