Unfortunately csPost is just single threaded. What are you using for your news articles? I did do a modification for someone where it allowed you to insert an ID on a template so that it generated a unique 'post' per unique ID. You can email me directly at firstname.lastname@example.org if you want to discuss this further.
I contacted both him and the person who had the issue but have had no feedback as yet..
Just wondering if anyone (a) can provide any help or (b) knows of another free cgi script that allows multi-threads comments?
