Playground partecipate

I'd like to add a new tutorial, but I dont get it, how can I do it ?

I’ve seen the partecipate section(http://playground.arduino.cc//Main/Participate), but where to go from there ?

you need to login and then you can edit pages.

For me my forum account works also for playground. There might be a restriction that you need to have a certain number of posts, I don’t know.

What tutorial do you want to add?

Oh now I see it ! Tnx.
But I want to add a new one, not edit...

To add a new one you must create a link on an existing page, and when you click it you get a fresh blank page.

What tutorial do you want to add?

PLease add this on top of the page:
