I followed the tutorial as best as i could and came up with this

.

i want to make the pink part sort of round, like a cylinder. but i have no idea how to do this. can someone please point me in the right direction?
This is my very first model btw.
Thanks!

convert that portion to editable poly. select the two edges that you want un-boxified. click the little box beside chamfer and select the amount. Chamfer several times for increased chamferage.

You should really follow my tuts: http://www.halomods.com/forums/viewtopic.php?t=18742
I'm not finished with that thing yet, as i will be updating. I'll be posting more in-depth tutorials soon.
