Simple Perl program but I don't know how to do it.

[copyright_1978]

Hi there, I'm trying to write this very simple message board in perl for my website but I'm trying to get the following functions to work:

Please note: I am using a simple text file to save all my work. IT's my database.

1. The user should be able to post a message that saves the details to a text file.

2. When another user want to reply to the message they should be able to choose the message that they want to reply to, so for example, by clicking on a message they should be able to reply under that message.

3. The user should be able to make a reply the subject. So for example if "I need help please" was the subject, and "I will help" is the reply, they should have an option of switching them around.

4. The user should also be able to place their replies in the order that they want, so for example, if they there was two replies, the user should have the ablility to place his message at the top, or at the bottom.

I have done number one, but I am having trouble with the rest. Can anyone please help?
