Well, cally.
First, it chooses the last thing you used(Question, PVP, w/e)
to make ti choose a certain one. Make sure ARelog is opne but Wow/HB are not running.
in ARelog do the following:
Click on the account you use, then press "Schedule Selected".
Press "Add". Something will pop up!
In Bot Name put the bot you want as it appears in Honorbuddy ( ArchaeologyBuddy, Questing, Grind Bot, BG Bot [Beta], etc.)
In Profile path, click it twice to make the popup come up so you can choose your profile. Click the one you are using for Questing, Grinding, or w/e)
In the Run Time box, choose how long you want it to run. Save & Close this.
Then, if you want this to repeat itself, Tick "Loop Tasks" But If you want it to do Grind for 4 hours, then Quest for 3, you have to set up two different tasks(by repeating the steps above)
Hope I helped
