It's theme specific. Some themes do not allow them as when Pages were originally designed, they were meant to sit outside of the regular post structure. That's why they don't normally get timestamps, categories, tags, and comments like you noted. Some theme designers throw them in though because they feel the same way you do.
Only real work around is to change themes until you find one that allows them.
Wish I could give you a better answer. James could go through and edit all of themes to allow them. Not sure how he feels about the subject. He seems kind of conservative when it comes to stuff like that.



I'd like my pages to have comments posted on them - not be static. There is an option to activate comments on the page, yet when I activate this, nothing happens on the page to allow people to leave comments. I've been trying to get it to work here. Please let me know if you have any insight.

Somehow this site has it working.

I contacted him, but all he could tell me he did was activate the comments selection on each page.
Anyone have any insight on this for me?
