If you are using a Xanga Theme, you can change the number of weblog entries that appear on your site by doing the following:

1. Go to your public site (www.xanga.com/yournamehere) and click "edit theme" at the top of your page (note: you must be *signed in* to see the "edit theme" link).
2. When you are in "edit theme" mode, you should see a little edit button (a pencil) at the top of your weblog module (in fact, you'll see it at the top of all your modules - you can edit any module on your page using these steps)... click that edit button
3. A little window should pop up showing you all of the available settings for your weblog module. To change the number of posts displayed on your page, just adjust the "Number" setting to whatever you want!
