Troubleshooting - Why can't users post more than one message at a time?

When the box next to the "Spam Control" setting is checked, users must wait a set length of time before being allowed to post another message. You may set this length of time to as little as 1 minute or as much as 60 minutes, or you may turn Spam Control off altogether. (To avoid problems of abuse, we recommend that you do not disable spam control.)
