Command alteration for Skyfire EMU

[iMeth]

Hellow OwnedCore. As you can probably tell, I'm a new member to this website. Registered a while back since the community is cool and offers helpful tips on server management, yet never posted due to lack of time, above other things. Anyway, moving on to the thread.

I have a question regarding a certain gm command on Skyfire EMU (Trinity Core), namely the .summon <name> command. Now, I'm not quite experienced with C++ editing or anything like that, but I know the following is possible because I have seen it implemented on other servers.

Basically, what I want to do is this. When a player tries to summon another player, instead of automatically teleporting the summoned player to the summoner, the summoned player receives a message "<player> is trying to summon you [Accept] [Decline]" as if they are being summoned by aWarlock or at a meeting stone.

As I've said, it's possible and I've seen it put in motion, but I don't know the exact way to do it. If you guys would be helpful enough to help me out on this one, I will be very grateful. Mucho thanks in advance.
