@Sen-Sai Thanks for sharing this creation. I am getting an error "please log in first." This sometimes shows up when loading the form, and also when trying to submit a form. After submitting the form no longer loads and just shows "please log in first." It also shows up on the documentation page for FlexForm.

Ah yes. I'll put that in the manual. By default only logged-in users can use/see/submit a form. What Cavils said works. When creating a form use the restrictions=lifted. I just might create a setting for it, to turn it on/off.
Example :
<_form action="addToWiki" restrictions="lifted" >
I had the same problem and solved it by adding restrictions="lifted". if you offer the form for editing pages, be sure though to make it available only to users you can trust (as opposed to, say, anonymous visitors to your site).
