Can I be invisible on the site?
With regards to invisibility on the site, no, you will always show that you're online if you're logged in.
If you are an XL subscriber, you have the option to set up anonymous viewing, meaning you can look at someone's profile and they not know that you viewed them.
If you have questions about a subscription, you can find those in your account settings section under your profile.
Thanks,
