Arduino Board Mega2560 + Ethernet Shield + mux?

Hello

I'm new to Arduino Borad and just discovered it few days ago.
I plan to buy some module, just one for the moment, just to see how it works and capapbilities.
My question is about Mega2560 and Ethernet Shield. Are this module plugable as easy as it is between Uno and Ethernet (just plug it above the first one) ?

My second question is : is-it possible to connect 2 shields ?
I mean, an Uno board for example, with Ethernet Shield and the Mux Shield (found on Lextronic website in options card for Arduino) ?
Or the best and simplest way to add some inputs is only to get a Mega+Ethernet ?

Thanks

Some shields you fancier together, some you cannot. This is because two sheilds might coincidentally both use the same port. Look at the specs of the sheilds and check to make sure there is no sharing. I have seen instances where thr PCB of a shield has been modified so that two sheilds will work together.

I have the same doubt: Can I mount an Ethernet Shield Version 5 to a new Arduino Mega 2560? Are the Eth Shield pins suiteble with Ard Mega 2560?
