Subsonic Forum

Better spam detection for the forum, anyone? Maybe a simple question like "which is the first letter in the word Subsonic" to stop them (until they get even smarter)?

We have better then that - which works, however it wont stop human spammers (unless colour blind )
After that they have me !!!!

Ah OK, I thought they were machines that slipped through (we had that problem at another forum I run, and it helped adding a simple question as the spammers automatic letter recognition got better). Thanks for tidying up!
