Not too long ago a new piece of content was added to RuneScape, a MMO I play. This suddenly made some ingame resources that so called workers would gather for you at a configurable speed (but a set limit) more important. As I tend to be quite forgetful about actually emptying these kinds of things I quickly set out to set up alerts for this. I could have gone with a very naive that would just fire after 7 days exactly or something like this, but that’s no fun.
