As you can all tell, we have upgraded the forums to vbulletin. The biggest reason for this change is that vbulletin allows us much better options to stop spam, which was becoming a bigger and bigger issue with the old forums.
As is always the case with a move like this, we expect that there will be problems with the upgrade. Please drop me a note if you experience anything strange with the forums.
This will take some getting used to but I'm so happy you are trying to do something about the spam.
Yes, you have taken a very important step to control spam. A right decision at right time.
