OK, that's weird - I started a thread to let everyone know about this and it's vanished! Hope I posted in the right forum, I'll have to investigate that!
There is indeed a new HobbyTalk Slot Cars Facebook page - we split the old one up because it was getting difficult to feature RC and Slot Cars and models and diecast all on the same page, so now they all have their own pages! We want to post links to great content on the forum (pics, threads, etc) to hopefully publicise the community on Facebook and make new people aware of it.
If you have any suggestions for stuff we should showcase, just let me know by PM! A couple of people have also already volunteered to help run it - thanks to all who have! And more content-posters are always welcome, so if you'd like to help out just let us know!
