This has been working for me,
There are a few changes from normal simple-follow setup you should be aware of though
1) You have to set one of your bots as leader in the plugin config there is a checkbox 'Leader' - this is saved with the settings for that bnet account, all other bots will be followers if they aren't checked as leader. (normally simplefollow designates a follower as a person running a profile with 'simplefollow' in the name - but in this case multiple bots are running bounty profiles, besides the whole start the leader first method seems bad to me, too easy to get messed up).
2) Turn on auto-join, and followers will use it if they find an auto-join link with the leaders name in it.
Instructions
Grab the latest version of community bounties because it has the reverse profile for act1 - so bots can be working on different bounties.
Load two diablo windows and two instances of DB
Set only one of them as the leader in plugin config.
Load act1 profile on first bot and act1_reversed on second bot.
Start both bots.
Things to note:
i am not using RYAR - no idea if that works or not. You can start a separate instance of d3 manually using a shortcut with "{path}\Diablo III.exe" -launch
i am using only two bots, no idea if more will work.
Not compatable with existing simple-follow you'll have to remove the normal one from your plugins folder.
Sometimes get out of sync with clicking boss fight join dialogs, if the profile is sitting there clicking the portal to the boss over and over again.
Inviting code for the normal social window send invite button is busted for me, maybe because my connection is really laggy right now. its working for me based on the auto-join only.
