Not that I'm crazy savvy, but I have been asked by more than one person for some help with Xanga 2.0. I will take a few screenshots and see what I can do as succinctly as possible.
#1. LINKING YOUR NAME
Many of you know this already (so skip this redundancy UNLESS YOU HAVE AN UNDERSCORE IN YOUR NAME because I've seen this over and over). When we leave comments, it's nice for our names to link back to our pages. Here's how:
Click Edit My Profile

Then scroll down until you see a place to enter your website. **IMPORTANT NOTE** If you have an underscore in your name, your new xanga site has a dash in place of the underscore. If you underscore your new link, IT WILL NOT WORK.
Type in your xanga site. OR if you have another site (if you aren't a paying 2.0 member yet) you can also enter it here and when you comment, people can still find you. NEAT!

Once you do that, don't forget to scroll down further and click the blue UPDATE PROFILE button (or the change won't save).

#2. FOLLOWING/HOW TO FOLLOW
In order to have stuff to read, we must now "follow" our Xanga friends. Here is how to follow someone:
On their Xanga page, look below their big icon. There should be a Follow link. Click it.

Once you've done that, they are now here in your FOLLOWING tab:

From here, you can also manage who FOLLOWS YOU (your followers)!! Click the Followers link and you can see who reads your updates. Like this:

#3. PRIVACY LOCKS!!!
This is the crux of many Xangan issues. Either you don't know how to do this or don't understand what the locks are. I will show you how to manage this, but I BEG YOU NOT TO USE FOLLOWERS LOCK!!!!! Please do NOT use it until there is a way to request becoming a follower from outside the approved list. Otherwise, there is no way in and no way of notifying the user that you're there. It's a brick wall and PREVENTS friends from finding you, reading you, messaging you, anything. This is not worked out yet with 2.0. PLEASE DON'T USE FOLLOWERS LOCK! But here's how to manage the privacy settings anyway.
1. On the left, with your mouse, HOVER over ADVANCED.
2. Click Privacy Settings on the drop box that appears.

From here, you have very basic choices. I have MY site set on sign in lock. Only Xangans can visit me. It doesn't matter what Xangan. Random people from the internet can't. It's my personal thought that this is the most secure option WHILE we try to REBUILD the COMMUNITY aspect of Xanga.
Because if you use FOLLOWERS lock, you will NOT be participating with the community. And BOO on you for that.
Use the drop down box to select the privacy setting you desire. And click Save Changes.

My brain is dead. I have no idea what else to guide about.
