Right now we have follow and escort for players following eachother. Follow runs into the simple problem that quite often, the person being followed manages to lose the follower due to the difference in PC speed. Escort, however, doesn't make IC or OOC sense to me if you're trying to 'guide' someone somewhere - as it relies on the person walking 'behind' the other for directional input.
My idea is simply a "Guide" command that would require a y/n or @trust from the person being guided, that allows the person inputting the command to slow their PC enough to allow the guided player to keep up, similar to how escort works, preventing the 'guided' player from losing their guide.
For example. Joe wants to show Jane a hidden route to a secret spot. Joe can type 'guide Jane', and if accepted, Joe will slow himself enough to allow Jane to follow him wherever. This prevents Jane having to 'escort' Joe, which as I mentioned before doesn't make sense, and also stops Joe outrunning Jane, as he's more 'focused' on guiding her than if Jane were simply following him.
