Inviting 2 team of 4

[Wubsie]

By default isboxer will just invite the 5 first toons since that's when it his the max party members limitations and it does not auto-convert your party to a raid. Jamba has an option for auto-converting, if you're using it.

For inviting your toons to 2 parties of 4 I think it's easiest to set up separate invite macros for both parties. I have mine set up do that Slot1 invites slots 2-5 and Slot1 invites 7-9. You can set it up full inside ISBoxer or with ingame macros bound to a key that you'll then make a mapped key for. Personally I prefer the first method of the 2

Personally I've set up a single macro in ISBoxer that lets me set up questing groups easily and is not hardcoded to only work with specific toons. Mine looks like this:

!if (character is"slot 1") /invite {SLOT3}
!if (character is"slot 1") /invite {SLOT5}
!if (character is"slot 1") /invite {SLOT6}
!if (character is"slot 1") /invite {SLOT7}
!if (character is"slot 2") /invite {SLOT4}
!if (character is"slot 2") /invite {SLOT8}
!if (character is"slot 2") /invite {SLOT9}

Very simple really, just an !if argument to designate which slots will do the inviting (1 and 2) and then ISBoxer works it's magic and replaces {Slot#} with the correct names. The order might seem a bit random, but it's due to me swapping some toons around for dungeons and whatnot.

The way you'd send this to your toons is through a Mapped Key with a Named World of Warcraft Macro Action.
