writing to Text file

[foo721]

I'm having a problem writing information to a text file that is being accessed from many machines. We made a flash game for a tradeshow and the machines are all windows so I wrote it to work on windows although
my expertise is linux.

So I need to make sure that if many people hit the submit keys at the same time, both names will be loggedd.

thanks

Use session id to identify users.

Should work fine.
