Can you answer the question in the title without looking it up?
I bet you can't and this makes the whole "contract" that you have to sign with your real name (lol) completely pointless.
Can we please remove the strict number "obligations" that anyways no-one is going to obey to? If someone likes the site they'll use it otherwise they won't. Making them promise that they'll post a certain number of questions or answers won't help anything.
I think the text should be changed to something like this:
By committing to this website you promise that you will try it out during the beta phase.
This is a much more realistic promise. And please no more "real name" signing. Just an old fashioned "I accept" button.
