More Calling Card Options

I would like to see more options, like the grant modify permissions, for calling cards.. Either in the properties of them or as right click options..

So you could..

Grant Find Permissions
Grant Summon Permissions (As Philip was talking about)
And the normal Modify permissions

ALSO if we are to need a calling card to summon people we'll need a long distance way of trading cards.

Let me know your opinions!

/agree

Also, how about having an invisible mode where you don't appear online to anyone, except for people you check the "always view online" checkbox?
