A Portly Senior w/Newtoy and questions

[Rondaboo]

I just started MM about two weeks ago and and have been really enjoying it. Such a pleasure compared to the

blowup everything and /or kill everybody

games that seem to be the

In thing

now a days. After having browsed thru this forum I do have a couple of questions about it; I see mention about 24 original mansions and room numbers. My version of the game has 8 mansions and I wonder how do you find room numbers and is it possible to add these other mansions, also is it possible to get 100% secrets?

Please bare with me folks since I am a 76 year old computer illiterate and have finally found a game I can enjoy and it appears there is even more to it.
