Hi folks,
We upgraded the wiki software at ifso.ie last night, as part of a move to a new server. As a result you can once more edit pages without being logged in; the new software has some anti-spam measures so we're going back to a more open set of permissions.
If you should encounter any problems please let me or the webmaster know. Many thanks to Michele Neylon from blacknight, who supplied swift and efficient support during the changeover.
