I hope that you liked the recent design changes in the forum. I've had some positive feedback from a few people so far, which is great. Please do let me know if there are any bugs/problems.

No more spam (well not for you anyway) :D
I'm very pleased to announce that the spam posts in the forum are now history thanks to an improvement to the forum software! Basically, all new members have their first post moderated before being published. Such a simple but effective improvement! It means that you won't have to see junk posts anymore. Unfortunately that's not the case for me - I still have to wade through them in the moderation queue. There are so many every day - it drives me crazy.
