Hack request for Trip report?

[attroll]

I searched the site here and I don?t see where anyone has ever asked or created this hack. But I have a need for one if it can be done. I am not that knowledgeable to do this hack myself. This is what I would like if someone can do it for me. I don?t think this is an easy hack. But I will ask anyway.

First let me explain what my board does. It is a hiking board. I want to be able to post a trip. Here is an example. I want to schedule a trip for the 25th of May and I want to set a limit of 8 people to attend this hiking trip.

Now I want people to be able to go into a messages section and be able to pick from the following categories one whether they are planning on attending: Yes, No, Maybe. Sort of like the voting poll section. Then I want these answers tallied up so it will display the answers to who has these votes and there names along side the answers. Then when the number of yes votes reaches 8 then voting will stop and a message will display saying something like ?Trip Full?.

I saw this on another site but I have added a few extra items to it. This is what I would like to be able to do on my VB site. You can look at what I mean at this other site: http://www.thebackpacker.com/trips/trip.php?id=18

I hope I did not confuse the hell out of everyone on what I want?
