Post to a html file
 

I am not sure if this has been done already or not but, I couldn't find anything via search. This is what I am hoping to get done;

In my forum people post news about certain topics and discuss it. News is always in a separate post in any given thread. What I am hoping to accomplish is have a check box on the post which once clicked, should take me to a separate form where I can pick a Day/Month/Year from a Calendar. This in turn will write that specific post to a file, hence a separate html/xml file for each month.

The reason for this is I am trying to compile news appear in a given month in a separate file. These xml files can be handled via database or any easyily manageable system....

Any help would be greatly appreciated.

Thanks
