You should always use a bottling bucket. That is a whole separate issue, which is why no one mentioned it probably. If you don't use one then when you mix the sugar in you will mix up all the yeast and trub at the bottom, and you don't want to put that in the bottle.
I think I read in Palmers book if you don't have a bottling bucket you can mix in the priming sugar and let it sit for about 15 mins to let the trub settle again before you bottle. Havent tried it, but I don't see why it wouldnt work. I poured a glass of truby beer and it settled out fairly quickly and tasted the same as the standard stuff.
OT im new to homebrew but I will be primarily making dark beers/stouts so im not worried about the beer clearing up to much but I will probably get another fermenter and a single secondary so I can have more beers going.
