After activating your account, you will be assigned a UID (User Identification) number, which will help identify you across the network. This number can be found in your UCP, or by navigating to your profile page and reading the address. Your UID will show as https://aows.tk/forums/members/[UID]
in the address bar. For example, Ricky Chatell's profile address is https://aows.tk/forums/members/2
, meaning that his UID is "2".
