Hello kevuk25,
It would appear that the last post is almost automated... it didn't really answer your question at all and I don't think that's too fair for people who come to a help forum for assistance.
Granted, mIRC is not geared for file sharing/trading, but I'm not here to give you a lesson on ethics.
To answer your technical question, I do believe that with probably some simple script programming, mIRC can be setup to prioritize users. However, your technical question is best suited for the programming forum.
I will see what information I can collect for you to solve your dilemma.
Regards,
John
