I seriously considered 3B for round 4 but I appreciate you letting us know so timely so that we can set proxies. Anyone interested in moving up in round 5?
You need to set the round you want. 4 for now then list all your proxies in order for group 1. Then you can set round 5 proxies but they must be listed as group 2. After that you put those in the order you want. I hope this helps.
You must also make sure to to say yes to removing the previous proxies from the group so that you don't accidentally end up with 2 catchers or something else.
