I grew weary of deleting Cialis (I should probably not even type that word!) spam pages from the Ancient World Open Bibliographies Wiki every day, so I have increased the level of security on the wiki, allowing only registered users to edit the site. Everyone who wishes to become a registered user must be approved by the administrator (me); I will be checking for requests daily. I hope this does not have a chilling effect on the user community; I can try re-opening the Wiki to editing by everyone in a little bit. Maybe the spammers will tire of us.
