when replaying to a messege, above the box you are posting in, and right under the person your a replying to. there are icons for commands. quotation, bold, italics, etc. the last crop has an icon with 1 player, 2 players, and a ball
player [player=XXX] insert his number where the XXX is
so its player=8077133 with square brackets.
to link a team you use the icon with 2 players
[team=XXX]
and to link a match its the last ball icon
[match=XXX]
hope that helped
