I got this idea from a very good friend of mine on another Website. I have tried it once and it has worked, but I cannot and will not guarantee that it will solve all of your problems! Still, its worth a try. Please post and let me know if it works for you.
She says "i've been trying something over the last few days re changing my room names & have had mostly success.
work out what the rooms are you want to change & where they are, log out then log back in
& go straight to the map & click rename then type in the new name without going into that room, click the next room you want to change & when it loads....again don't go in there or take the map off the screen , just rename it.
if you go into a room (except the very 1st time you click "go to my room" )it puts a stop to it all, if this happens log out then log back in
, sometimes this won't work for a 2nd time but if you log out & stay out for a while ie maybe 1/2 hr then try again it may work.
I've been playing with all of this for days & don't know if i'm just lucky all the time but if I try it any other way I keep getting the message i've used dots n dashes or words not allowed.
hope this helps some of you"
