Frontend add category form

Flexi content is most amazing joomla modyfication ever! But I need one feature, that I can't find. I want add category in frontend. I must do this in this week, so If anybody can help me I apreciate it!

Hello

what is the usage scenario for adding category via frontend ?
i mean describe the web-site

User don't want login in backend. Site must be very simple. He want add content only in frontend. In this site joomla menu ids not used, menu is build from category structure replaced standard menu structure. If user can add category in frontend that is all I want reach.

Same need for me...something new ? Thanks

Hello

What about adding this:

Auto create new category at top level
inside item form via category selector (same like tag creation via tags selector)

Yes would be a good thing, although my customer would prefer a form to create as much categories as he wants.
But your solution would be ideal too.
