Insight: Are we going to be using IC for rolling, or are you going to handle all that yourself? If IC is used, how would you(and the other PCs) like to handle Commander's strike? When I do my action would you like me roll the other PC's granted basic attack or let them handle it? It would be faster probably if I did it, but the PCs might prefer to do it themselves.
Yes, I would like to use Invisible Castle for rolling.
It'd be easier if you rolled everything for powers like Commander's Strike. It will require you to know their attack bonus, however, so you'd be wise to check that before posting rolls for other characters.
The same goes for any power that causes another character to attack. The only case where I can see having the affected character post an action would be if your power allowed them to move or make a non-attack action. I guess using a Warlord in a PbP game requires everyone have a bit more trust.
