For an Apple device: Open Game Center, click on Friends at the bottom of the home page, then the plus symbol in upper right corner. Type in the person's Game Center name (which I think may be what you're calling username) and then it's polite to add the optional message, such as "DragonVale coop breeding" or "DV daily Gems" or "DV party hats only", something like that so they know why you're requesting to friend them.
