Added; hopefully it worked. For dice rolling, RPoL has its own die roller; I'll put up a sample action in the Character Creation thread to hopefully make it a bit clearer on how to use.
As for Affiliations, you pretty much have it. If you want a character who works great as part of a duo, sucks when he's by himself, but can manage playing in a team, you'd be Team d8, Buddy d10, Solo d6.
You will always get at least your Affiliation dice and your Distinction dice (Paragon or Renegade if nothing else fits). The rest of your dice pool is built by relevant Powersets and Abilities (Knacks, etc).
A sample action will help, I'll go do that in the thread when I get a chance.
