In reply to Route Adjuster:
As someone who has done a bit of both (moderating as well as submitting new routes) I can only say that the more information the better. It's no good just dumping a route in without an explanation.
If it's brand new I try to put everything I possibly can in to furnish the description.
If it's existing then I try to qualify the entry with the source of the route (ie if it has been missed off but is in a guidebook then I say which guidebook it is).
In all cases I will drop a line to the moderator to warn them that new entries are coming. They are much less likely to arbitrarily delete them. However, it has happened on occasion!
PS - to answer your question - ask for more info and if none is forthcoming and there is no reason to keep the routes then get rid.
