Here's a pretty good PowerPost Tutorial with screenshots. If I recall, it's the one that got me started.
I've seen problems with par sets generated by PowerPost, so it's better to make the set with Quickpar.
Also, since you wouldn't be posting FTD's releases

The .nfo should come first, but A&A 11b wants to put it last, unless I click "Sort .PXX" under the File Order tab.
You should put your handle in, instead of using the default of PowerPost-blahblahblah. (I hate seeing 20 or 30 guys named A&APowerPost). Thats "nickname" in the headers tab.
Edit: LOL! Ya beat me Arnie.
