Trinidad sandbox or any other place where to find components added by Trinidad users?

Hi,

Somewhere on the Trinidad site or JIRA there is supposed to be an area 
where 
to put and get components developed by Trinidad users.

Actually, where is it? I did not find. However, I think I remember someone 
wrote in 
an article on Trinidad that there is one, is not there ? .. ;) 

Many thanks,
Wolfgang.
