Well done for bringing this to the fore James - we do indeed turn 20 in early November of this year.
Apologies for the lack of content and ideas for our 20th celebration - life has been taking over my Porsche-based enjoyment of late but yes, we need to mark it!
We had a wonderful thread sharing our memories of the first 10 years. Have a read. They'll be some missing images and broken links but it will give you a flavour of back then

We also made sure that we marked the occasion of the 10th anniversary by raising £10,000 in that year and have continued to raise money - our Just Giving Page is just under £37K now!

Plus with other karting and giveaway cars (remember those) initiatives we raised in excess of £60,000 which is just wonderful.
I have an idea for a member participation activity which will not only create wonderful content, mark our 20 years in style, include members all over the country and hopefully raise some more money for charity - I have the embryonic bits sorted but need to do a little more work but will launch it soon. I think you'll all enjoy it. I hope so and it would be great to see you all getting involved.
And yes, a T shirt needs to be sorted, will get back on the case with that one.
