Newbies and Confused People - Look Here!

[FadingSuns]

I love this game at the same time it makes me want to drink. Anyway, here are some newby questions, I apologize if they've been covered elsewhere, but I wasn't able to find them in the forum.

1) I just got cool army 'X' stomped in a single player scenario. How do I go back a turn to change my armies orders so I can try for a better result? You know, the handy save move that every other strategy game under the sun has.

2) I just created cool mod 'X'. Where do I post it so other folks can take a look at it? Noticed that the New Mod forum on Shrapnel Games doesn't have a Dom2 thread.

3) Where can I find the preset alliances in a map? An earlier posting said that computer players can be setup at the start to have alliances with you. Where is this visible?
