You may want to change your username or the username(s) of your TAKEN Child(ren) especially if you are having trouble tagging them in posts.
The main menu is in the upper right corner of the screen.
All usernames on the site must be unique. No two accounts can have the same username. If the username is already taken by someone else, the system will tell you.
Change your username to something short. Try your first name only. Try your first name and your last initial. DON'T USE SPACES in your username because it makes tagging more difficult.
Tap inside the username field and erase what is there and replace it with a short, simple username without spaces.
Tap anywhere else on the page (like the blank area above the username field) and the system will check to see if that username is taken. If it is taken, the system will say so and you'll have to choose something else.
TIP: Keep choosing the shortest username you can until the system reports that the username is available for use.
If you've changed your username to the shortest possible username you can think of -and- that username is available, WOO HOO!! You now have an awesome username! If the username you chose was unavailable, try another one by repeating step 5 above.
