This has been posted on the main WebTRIS news site but also here for convenience.
Some users may have noticed we had a recent spam attack on the forum. A number of accounts were created and thousands of posts were added to the forum. As such we're changing the policy settings on the forum side of the site.
New Topics (aka, threads) will need to be approved by an admin member (this is live now).
New Posts will need to be approved also, although this is envisaged to be a short term change to be removed (this is live now).
New accounts will need to be approved by an admin member (this will be deployed shortly).
Regards, WebTRIS team.
