Greetings. You may have received a blank "Last week's most popular topics." email from ourselves a short while ago, that's my fault sorry. There's a development version of the forum where I have freedom to make changes to the forum without actually effecting the live version, if I break something it's easy to just drop the whole development forum and restore a recent backup. But I forgot to realise that the backup I restored would have access to our email server which then resulted in a random "Last week's most popular topics." being sent. Sorry about that, I'll make sure it doesn't happen next time.
