Use of CAPS seems to be a matter of style and clear communications to me. Some people seem to be overly sensitive to CAPS. I don't use CAPS for everything, only for things that I want the reader to pay attention to.
But it is YOUR product/wiki. Please feel free to edit any of my posts to YOUR wiki to fit YOUR style.
Just so you, and everyone, understand my style, I do NOT consider use of selective CAPS to be "shouting". I consider it to be the same as when I am talking to someone, and I want to emphasize a certain word or phrase. In real life, I don't think I ever shout at anyone, except in case of extreme emergency.
OK, you know me, I like a little bit of formalism on the wiki (being a pedantic sod is part and parcel of being a Mac developer I guess). I’ve changed them.
