how do i acess them to see if any1 commented on them?

you have to track your topic...

If you tracked those topics, then click on the topic tracker button in the top right corner.

If you didn't track those topics, then there isn't really an easy way. You'll have to go through the pages to see if anyone commented after you did.

When you make a new post you have to check mark the "track my post" thing
By the white arrow

This, or if you've already posted, you can click the Track Topic button at the top right of your post.
