hi! welcome to pt. there is an FAQ which u can look at but pretty much, u get mithril for logging in the first time in a day and u can use mithril to send private messages (pm's) the weather effects the cost of ur sending, for example if it is raining it will be more expensive then if it is a nice day. same thing pretty much with the locations. the closer u r to someplace else than its cheper to pm ppl in that place. also for 400 mithril u can switch locations.
c u in the threads!
