Actually, already and alright are used often in english courses/books in universities today, along with business and various journalistic publications. The words were once the separate words of all ready and all right, but have evolved to be already and alright. You can find them in the online Webster's dictionary:

Already: http://www.merriam-webster.com/dictionary/already

Alright: http://www.merriam-webster.com/dictionary/alright

I totally agree about accept/except & affect/effect. When people say your instead of you're, or there instead of their, it drives me crazy.
