I do love to be courted!  Flowers, chocolates, dinners, bring it on!
How long do you think is appropriate for courtship before deciding whether the relationship will lead to an engagement or marriage?
I'm not certain it ever has to end up as either.  Depends on how things go in the courtship
I agree. I usually know after about 3 dates whether I am compatible with the person and want to continue pursuing the relationship. 
Perhaps a relationship isn't always the desired end though.  Can't people just enjoy each other's company and the fun of a courtship?
I imagine that depends on your goals; whether you are courting for fun or looking for a serious relationship that may lead to something more like marriage. As long as both people are on the same page, I see nothing wrong with that. 
I agree.  I myself don't want marriage, a live-in or somebody around 24-7 however, I do like having somebody to do things with and who is fun.
You're right. Dating is a nice way to socialize and have company without the burden of a serious relationship.
