Mods? Maps? Need some help

[GrudgeBringer]

OK....I am somewhat computer challenged although I have been able to figure out how to upload a Pretender and do turns (and revised turns)in a MP game.

But I seem to be stuck on a couple of things.

You would think that the description would be enough (and I think I know the answer) But what is the difference between a 'MOD' and a 'MAP'.

I take it a map is just that...a map that you can install and use in a SP or a MP game.

A Mod is changes in the gameplay if I am correct.

Now my problem,

I have read every post where it says to put it.

But I get confused beacuse of the terminology (told ya I was 'challenged').

I have D/L (and could someone link me up with this Worthy Heroes agian please) KingMaker and Worthy heroes to desktop.

I then tried to open them and nothing (it says I needed a program to open them). I DID get worthy Heroes to extract one time and I extracted it to the dominions Mod file (where I made another file inside saying "New Mods") and then happily went to the prefrences to see my new mod and nothing was there.

So, Could someone that has the patiance to teach someone on a remidial level PLEASE explain it to me in real words so I can try and play MP that doesn't use vanalli maps and no mods.

Thanks Guys I am really getting frustrated.
