That’s the way the cookie crumbles.
From Tuesday, 1st May, 2012, the policy for user comments on RISCOSitory.com is changing, and Google adverts will be disappearing.
Previously, any user who wished to comment on an article needed to sign in to post their comment – which, obviously, meant they first needed to register with the site if they hadn’t done so already. In addition to that, there was a very simple moderation policy, though it wasn’t stated anywhere: Any comments including links needed approval, and any individual user’s very first two posts also needed approval – after that (and subject to the comment including a link), their comments would be automatically accepted.
From 1st May, however, registration will no longer be necessary.
