Summons <player> to the same channel as you. This code is untested

[cen1]

This seems potentially dangerous and abusable. Is it supposed to be under higher CGs?

[RElesgoe]

Yeah, those with higher CGs should be able to use it, not regular players

[HarpyWar]

May be add this command and allow it for all users, but destination user must confirm it by writing /summon yes (the same syntax for /clan command when invite user into a clan)

[RElesgoe]

@HarpyWar I disagree, if a player wants another player to come to the same channel, he can just /whisper the other player to come and if the other player wants to accept the request, he just types /j <channel>.
