Where to put shaders

Hey im new lol this may seem like a really stupid question but u know the shaders? like Chrome etc.. all on this site? where do u put the files? and how do u get them to work? please help..

import them or drag and drop them on the main maya window and they will show up in the mulitlister or hypershader

I believe what they are asking is:

Does Maya have a default location to save the *.ma files so they show up without having to drag the file into your scene everytime?

No! Maya deoesent work with a library of materials (like max for example, thank god for that)... Altough you could make a file tab in hypershade! Wich would effectively do the same thing (altough concievably in a more convinient way). But its still just the same drag and drop operation.

Use whatever directory your heart desires.
