Message formatting...

I would like to always see the username who sent an IM to me, even if it is 2 or more consecutive IMs I always want to see the username, but I have forgotten where this option is [and can't find it] any thoughts?

It is now entirely up to the message view you use.

I suggest you take a look at http://www.adiumxtras.com and try to find a message view that better suits your needs.
