I have more ideas than time and now I added Mini treasures to Twitter:
Mini treasures is using already quite many services:
the wiki itself is in PBworks
the wiki news are told here in Blogspot
the photo group is in Flickr
the video group is in Youtube
the fan group is in Facebook
and now the Twitter account is for sharing quick notes about the highlights.
The most active of all is of course the wiki, the other places are created for promoting the wiki to all miniature lovers in the web.
