MemoirSite incorporates a fantastic feature that we call the Lifetime-Timeline. Every entry appears on a banner-style calendar that you can scroll through to quickly access any of your posts.

Say you want to add to an entry about a memory from a couple of years ago. Go to the Lifetime-Timeline page, then double-click on the year you want. Grab the month bar and slide it until you home in on the post you want to edit. Click the dot on the Timeline, then on the title in the popup box and you are ready to write.
