hi!
i think about developping a free software for Trading-homepages.
i think about a dynamic php script which do save all data in a database.
is there already a good solution available?

i searched for other systems and i really like these:

http://www.myhobbysite.net/
looks like a great system, but i think this is not for free use!(?)

www.mn-trading.com
looks great, too but is not available becasue the coder do not want release his sources

do you know other sites using already a similar system?
Before starting developping i want check if there is not already a software for this and collect ideas how the new system should be work.

thanks
