Bot1 is your most stable bot and this will be your hub bot.
Bot2 is your second most stable bot and this will be your alternate hub bot.
Bot3, Bot4, & Bot5 are just leaf bots.
Bot1 should not need a flag set as it is your hub.
Bot2 should set Bot1 with the +h flag i.e. .botattr Bot1 +h
Bot3, Bot4 & Bot5 should all do the same and set .botattr Bot1 +h
Now Say that Bot1 happend to go down the other bots will need infrmation on which is the alternate hub bot so in Bot3, Bot4 & Bot5 you should .botattr Bot2 +a so all the leaf bots now know which bot the should connect to if the main hub bot is down.
I hope this helps.
The lifecycle of a noob is complex. Fledgling noobs gestate inside biometric pods. Once a budding noob has matured thru gestation they climb out of their pod, sit down at a PC, ask a bunch of questions that are clearly in the FAQ, The Noob is born
