This is pretty fun ... Makes you look like you in a go kart sort of thing.
If you type /sit then move and hold forwards (You may need to let go then rehold) your char moves about and everyone else can see it!!
The second you let go of forwards your char stands up tho.
Don't know if there is any exploit you can do while using this. We just had about 20 of us all in kheshatta doing it and I asked my friend to upload the vid. So I may add link to vid later.
