Login and Menu option?

I created an account “silverblue” to post here on the forums, but it continuously tells me my password is incorrect, even when I attempt to reset it by following “to the letter” the email that is sent to my email address. Frustrating, but hey, at least it’s something.
My actual question regards a possible plug-in/hack.
Like many, I’ve dropped MT and moved over to the more superior WP. One thing I miss from those days, however is if you were in an individual archive, the top line would be the subject/link to the previous post, one back to the main page, and one to the next post’s subject/link.
Is WP able to do that natively, or is that a hack, on the to-do list, or just considered “silly”?
