I have just been having a look at the new State Library of Queensland family history digital noticeboard. According to the web site (http://slq.nnub.net/):
"The SLQ family history Nnub is a trial project providing a digital community noticeboard for family historians in Queensland. Anyone can post. You can use it from the Web or from the Nnub touchscreen in the Micrographics area on Level 3 of the State Library."
