to be fair - if your interest lies firmly in the retail fireworks sector the you will get a whole lot more info from UKFR than you will from UK Rocketry, the clue is in the title....
There is a large event going on in April - not too far from you in Norfolk actually - a friendly competition between 4 or 5 teams using JUST Cat3 material, followed by a couple of Cat4 demonstrations - should be fun!
I could tell you more, but reckon you should join UKFR to find out

I'd signup to UKFR now but they only accept PayPal and because of my age I'm unable to open up an account. I normally pay for things directly using my sexy VISA Electron debit card
Cheers for the info, much appreciated!!!
UPDATE: I've Just signed upto the UKFR for 3 months. Ill signup to their forums once my account is live/active.
