Hi Steve and Ali,
The original post for the event has the title "Cockleshell Heroes Challenge at Eastney Cruising Association June 9th and 10th" and was posted on 19th April. Its near the top now so easy to spot but you are quite right that it's easy to miss things. Did you know that you can get a notification of new posts sent to your email? On the forum go to the home page and select the Options pull down. If you select Subscribe via email you get lots of options. Perhaps best to choose 'new topics' as otherwise you get every single post!
Also the diary on the main website
https://sites.google.com/site/langstonecutters3/home gives you dates for things to look out for so you can plan ahead. Hope that makes sense! Not sure if there is still space at the weekend will leave Dave to answer that bit.
