OK. I KNOW others will agree with this. I personally think that before a friend teleports to you, you should have yo click an accept button or something BEFORE they teleport. It really messes you up sometimes.
You'll be glad to know that we agree with you, but we've implemented this in a slightly different way.
COMING SOON, we will be adding Privacy Controls to Wizard101. These control whether or not you accept Friend Requests, Trade Requests, Teleport Requests and Group Invites. You can test this now on the TEST REALM but this is currently NOT in the Live Realm.
Lol, I guess they added that feature of being able to turn the teleporter on and off since I started playing a few weeks ago ... most of the time, I have my Trade, Teleporter, and Add to Group option as inactive, and sometimes I forget about that as soon as I ask a friend to port to me for help with a dungeon. :P
