In a full ring game where you believe that you have a positive expectancy, posting in the CO is just fine. If the table is that juicy, you could even post in MP3 or MP2. I've also heard the advice that, when playing small stakes live, it's okay to post from any position as that presents a friendlier "just here to have fun" image to the other players; personally I don't agree with that.

What it basically amounts to is, if you post in the CO on a full table, you are spending one extra SB in order to be dealt into 7 more hands (6 more hands if it's a 9-handed table). If there are one or more donors at the table, that's 7 extra chances for you to exploit them. On the other hand, if the table doesn't look that great, you might be better off just waiting for the blind to work its way around to you.

In a 6max or short-handed game you should just wait until the BB to post.
