I need to develop a membership site where members can register riders and horses for events. I need help with the database design (various CCT tables) and the relationships between them. I also need help with forms and lists. I will do a lot myself but I need some help when it comes to difficult relationships in the lists (see db design). I don't need help with design and UI. I will do it myself. This is just a prototype at the moment. I have a draft of the DB design and I have started with some CCT:s and listings at the site but it can be changed if you have a better suggestion.
