Wikis for specialist groups

I could imagine that Wikis could be a very valuable tool to enable participation statewide for specialist library groups. There are a number of specialist groups endorsed by the MPLA such as the Document Delivery Group, the Multicultural Group, Home Library Service Group etc which meet regularly in the Sydney metropolitan area. Obviously this would limit attendance for those libraries not located geographically within convenient travelling distance. Wikis would provide the opportunity for members of the groups to interact in current projects, without the need to attend every meeting. For example, I am involved with the Home Library Service Group and a few years ago we did a survey of Home Library Services in NSW. This was a very long drawn out process which could have been streamlined by setting up a Wiki. The survey data from the Libraries represented at the meetings could be set up as the original data. Notification would then be sent to all libraries statewide to contribute to the Wiki entering the information relevant for their individual service. Their may be a need to set up group membership with an invitation key to control access to the Wiki. Most groups are restricted to quarterly meetings each year which seriously limits the projects that can be undertaken. The idea of interactive sites, Wikis, Blogs etc could allow greater membership with regular participation throughout NSW from all members, and enable the group to commit to more projects without the need for more meetings.
