I was messing around with pisg, which is the best open-source statgen there is, and I decided to use an eggdrop to collect the logs. I installed it, and began gathering logs, which pisg processed, and put on the webpage. Now I noticed that eggdrop made a .log and .yesterday file, and I also put a link to those 2 files on my website.
At that time, I was looking into the configfile (once again) and noticed that using this configuration, the logs wouldn't be around forever.. you needed to enable a special option for that. But when I did so, there was to .log and .yesterday file anymore

Is there a way to keep logs forever, and still have a .log and .yesterday logfile?
