Hmmm.. I guess the best way to do Reposte in PbP would be for you to declare it before-hand since you wouldn't ever want to do Reposte if attack-roll had a high number of hits since it does more damage. We'll make it just a standard parry and then you can take your 2nd IP attack. In the future, when in melee with someone, declare to me if you want to do a Riposte at some point before you get attacked. Then once you riposte, let me know if you want to do it for the next attack. Does that work for you?
