Site builder

I’m fairly new to website building and have an idea for a site where users can add input and other things on the site,sort of like wikipedia allows users to edit articles,Anyone know how that works or what sort of program it is?Also what is a good site builder/host that is fairly easy for beginners to use?Would Yahoo site builder be a good choice?

Thanks

See I made an entire website on the supposedly free yahoo site builder and then when I clicked publish it said I needed a yahoo web host account, so I went to start an account till I found out you have to pay for yahoo web host, so I’m pretty much looking for any help I can get. I did all the work on yahoo sitebuilder and I really don’t want to start all over. PLEASE HELP ME!!!!!!!!!!!

I’ve created a game site with downloaded swf files from all over the internet (games downloaded/uploaded with consent) I’d like to be able to allow users to compete against one another for high scores. From what I understand, this requires adding a small snippet of code to the swf files, as well as a little extra coding within my website so that scores can be saved and published.

Also, a few of the games I’ve downloaded do not give credit to the author. I’d like to be able to add that to the game as well. (Give credit where credit is due!!)

Does anyone know of a program that I can download so that I would be able to add these things? I’ve downloaded 8 create flash programs so far and none will work. Maybe flash builders aren’t what I need??

Thanks in advanced for any help you may be able to provide.
Hey - Thanks for the fast reply. *giggles as she sees the e-mail addy to contact owner of the 2nd site*
So back to the question at hand… anyone know of a FREE decompiler. For the life of me I don’t understand these shareware programs that aren’t functional.
