why do you need a poke plugin, to poke more then 2 clients?
if yes: you could use the all new ts5 client!
like: just left click on someone and then press ctrl + left click, so you can select multiple people, and perform “multi -actions”. the same goes for a left click on one client and shift left click on the other client, it will also select all clients in between.
(would be an alternative, if the plugins do not work yet)
