[TYPO3] Enable editing og some Flexible Content Elements for all visitors?

[Redvald Hjulstad]

Hi,

does anyone know of a solution that makes it possible to have the 
content in some FCE possible to edit for all the visitors of a website, 
without the need og any registration?

What I try to do is:
Have a page listing some locations for off-pist skiing
Each location is a FCE with Name, Description and maby a picture
Let the user that was on that location the last time have the 
possibility to post about the weather, snow, etc.

Thank you!

Redvald
