I don't believe there is an area dedicated to truebox.
While a lot of users do box their characters on a single computer, there is nothing from stopping a player here using MQ from boxing using multiple computers. With that said. MQ isn't supported on truebox servers and therefore the software won't be of much use to you in that respect.
In regards to boxing manually using multiple computers my brother does this without the use of any software.
It has a lot to do with planning ahead, making hotkeys on every character and heavy use of
/follow
For him, he's using 6 laptops and multiple bluetooth keypads with group members hotkeys setup in such a way that a key on the numpad corresponds to a hotkey on the character. The cleric for example may have a 0 - 5 key assigned to target a specific group member by name and cast a preferred heal, or no heal at all and a subsequent one of the hotkeys on the numpad (6 - 9) correlating to a casted heal.
On melee or other casters it may be a
/assist mainassist key and some multi-binds to assist with attacking, where he uses the "driver" toon to position the other group members by walking past a mob and then facing it, placing the boxed characters behind the mob. In the cast of a mezzer (enchanter?) you want to setup your numpad to do something like target a mob on the xtarget window perhaps that way you can mez/do other crowd control.
It's a lot more difficult to it manually obviously. But perhaps starting small and working your way up would be less overwhelming than trying to achieve a full group of characters on a truebox server. Make a tank and add a cleric and enchanter to the group. Then use the tank to fight, cleric to heal, and enchanter to address ads. Play around with the setup a bit until you're comfortable with it and then add in some DPS.
MQ doesn't work on Truebox servers
MQ is not supported and does not work on Truebox servers. DarkPaw Games doesn't want multi-boxers, and we don't want to upset the official devs.
Other tools such as
MySEQ are available for truebox servers.
