Stats site with multiple login from hundreds of users

[quibbie]

I am looking at building a website that will allow people to sign up and post stats every week about others. For example, Joe has a show dog and likes to compete so Joe comes to to the site and posts.

Dog Name:
Breed:
Weight:
Skills:

Week 1: Fastest lap time:22.62 Highest Jump: 4'9 Fastest 25 yards: 2.43
Week 2: Fastest lap time:21.42 Highest Jump: 4'10 Fastest 25 yards: 2.33

Total: Fastest lap time:xx.xx Highest Jump: x.x Fastest 25 yards: x.xx

Any ideas would be great or a script if anyone knows of one.

Must support large scale logins.

Thanks a million.
