Re: need some help in usenet
You need to get a premium provider like Astraweb which currently has 1,083 days retention. You can try it out by getting a block account: 25 GB for $10 or 180 GB for $25 (there is no expiration date for these block accounts; they last until you use it up).
ISP on the other hand frequently only offers short retention times. My ISP, which uses Highland, only offers about 60 days retention.
You also need a site to search for the games; read this thread:
