Not quite sure what you mean but ok. Go to
My Account and try uploading some images (avatar, personal photo, desktop screenshot) in the Update Images section, it will tell you what size and format the images must be. Looks like you've already gotten the personal information filled out. I'm not sure what's up with the guestbooks, it's not showing up for some people for some reason. Maybe a glitch? Other than that just play around with stuff.
You can also go through the gallery section and add skins you like to your Favorites list. Under the skin description details will be a few links and stuff, one of them is Add to Favorites.
As a subscriber you also have the
Photo Album to mess with. Go there and click on Photo Management and you can start setting up albums and uploading images (has to be done in IE though).
