How do you command followers?? I tried holding E and it just went into convo mode. I tried saying "I need you to do something" and I got a pulsating curser that said "Wait here" but there seems to be no way of giving the other commands..

The pulsating move here thing is it. If you want them to attack someone you point the cursor at the person/animal. If you want them to climb on your horse, loot a body, you point and press E. ^.^

Point at their head and hold down E to access follower commands quickly. Pointing at their body and holding down E doesn't register 90% of the time.

Climbing on my horse? All I got was 'attack Stugfugley's horse' when I tried it....

Never owned a horse, just presumed it worked. Followers cant ride horses? Oh skyrim, you so svcky
