I can only approved, no rules.
Another armory suggestion:
Also add a commentary field for each armory item which can be filled in by the lender or the armory managers. This will allow experienced players to provide hints about the item the new plays borrow. For example, it might not be obvious to everyone how to use Espada Eslavona correctly. Or when to pick Tatars over Bodkins, for instance. In this field, you can also write details about the borrowing, such as: "Please give it back after 3 days so someone else can try it", or "Don't borrow if you already have 3 items or more", or "This costs XXX gold to borrow per day because (...)".
It is obvious that only a fraction of the players will use it, but introducing this should not bother the people who are not gonna use it themselves. It's like a new helmet, or so: If you like it, you use it, if you don't care, it does not hurt you.
