how do i upgrade my age status to adult

[valerie Inshan]

Your age is based on the birthdate you gave when you created your account. There is no more age verification process since July 2012. If you are over 18, here's how to update your maturity settings in the viewer's preferences:

How to change your preferences to view adult content

Even if you are 18 or older, you still need to opt in to view adult content. 

Tip: At the top of your Viewer, you can choose Help > About Second Life to check your Viewer version.

Log into Second Life, then follow these steps in the Viewer to set your maturity preferences:

1. Choose Me > Preferences (or Ctrl-P) and click the General tab.
2. Choose General, Moderate, Adult from the I want to access content rated: dropdown menu.

   

3. Click OK.

Congratulations! You may now visit any publically accessible land in Second Life, regardless of its maturity rating.

Note: If your preferences are not set to allow adult content and you attempt to enter an adult-rated parcel or region, you receive a prompt allowing you to either cancel the teleport or instantly update your access preferences to General, Moderate, Adult.

Getting Payment Information on File

Landowners may also restrict access to their land to those with payment information on file with Linden Lab. If you have purchased Linden dollars (L$) or bought something on the Marketplace, you already have payment information on file.  

If you do not currently have payment information on file, or if you are unsure:

1. Log in to your Account page on the Second Life website.
2. Select Billing Information under the Account section on the left side of the page.
3. Select Add Credit Card or Add PayPal.
4. Enter either a credit card number or a verified PayPal account.

Setting up a payment relationship with Linden Lab does not constitute a purchase; you will not be charged for placing your information on file with us.

Note: Linden Lab only accepts PayPal payments through Verified PayPal accounts. Please check your PayPal Account Overview page or review the PayPal support documentation to ensure your account is a Verified PayPal account.

I will add to Valerie's answer:

If you are NOT 18 or older, please do NOT attempt to lie about your age.  You WILL eventually be found out, and  the consequences are severe.  The very least that will happen is that you will be permanently banned from Second Life.   Many other, much worse, things can happen.  I'm sure you can think of some if you put your mind to it.  Do the words, "grounded for life" help at all?
