We've been getting quite a few emails about this subject, hence this snippet. Walnut Creek aka CDROM.COM is going to stop providing free mirrors for commercial archives - which is quite understandable. After first hearing about this last week we fired off an email to maintainer Ty Halderman of the (non-commercial!) Doom archives there, and he wasn't aware of any changes in the current status of our beloved archives. So rest assured... unless we hear otherwise in the near future all Doom files at CDROM.COM are safe.
