sure, some brewers ferm in a bucket but most use carboys/better bottles. If you're making 5 gal batches then ferm your brew in a 6.5 gal. If you only have a 5 gal then rig up a blowoff tube. If you look up at the top of the forum next to the "new posts" you'll see a "search" function. You'll get lots of help with that.
I was going to buy a brewing kit ie: buckets and all except kettle. I have a 5 gallon stock pot (im a chef I have these in numbers) and a guy at work got me into home brewing and has extra carboys he will sell me for ten bucks a piece. So all in all I dont need the buckets now its just nice to have them around just in case. I know ill eventually get some but for now Ill be brewing the dark stouts Ive loved for so long now.
All an Ale Pail is... is a food grade bucket. One that had pickles in it previously might be gross... but any clean, un-scratched bucket of that grade would work. THen just get an airlock, drill a hole in the lid and put in a rubber grommet... and you'd have an ale pail.
i use the ale pale to grind grain into, and the bottling bucket to soak items in.
glass carboys are fine to ferment in. i've been using five and six gallons for primaries. just rig a blow off on the fivers. and to echo bill, put them in a milk crate for the love of all that is holy!
