Other than sending Private Messages (PMs) there is currently nothing on which to spend your ever increasing Mithril. Be that as it may, we do have a thread How much mithril do you have?
where you can brag or commiserate about the amount of mithril you have collected and can also speculate about what you might be able to purchase with it, were it converted to your local currency.
