Regarding fights with each other and DM controlled creatures:

I highly suggest you either get private convos going if a fight is between the two of you, and send a PM to me if you're fighting a creature I control. I will reply with the results in a basic form, and you can integrate them into your post. This avoids you having to wait for each other's posts and keeps the combat fluid.

This option is a little more difficult to execute in a group fight, but I'm sure we'll manage.
