Unless you're experienced in making profiles I highly suggest that you use premade profiles which you can find in the GB section of the forum! To use the profiles simply download it and then you have to upload it to either
http://auth.gatherbuddy.de or
http://auth.gatherbuddy.com , logon with your account name and password and upload a profile and they should now appear in GB when you press refresh list. Load the profile and you're ready to go, assuming you have set up the required action bar in wow. You need click to move, locked camera. I suggest you go read the
Manual
action bar 3 should look like this =
1 - Flying mount
2 - Engineer cloud sucking
3 - Food or Healing potion
4 - Drink or Mana potion
5 - Bar 5 is used after you resurrect, hence it should be Shadowform/Aspects/aura etc
6 - Fight key 1, is used on engaging the fight and then every 10 seconds
7 - Fight Key 2, is used after fight key 1 and then every 6 seconds
8 - Fight Key 3, is used when engaged in a fight, pushed every second
9 - Pushed every 5 minutes, I would recommend this for short term buffs
0 - Key is pushed every 15 minutes.
