Go to Google and type in there usernmame and the word "Armorgames" and the first search result should be there profile.
That won't actually pick up any new users until the Googlebots have a chance to crawl their pages. The best way is actually to type in the username for the profile page link.
It works because the Googlebot crawled the page and added it to the search. A new user (hence a new page) is least likely to have been crawled and would not have been added to the search. It would not search the newest users but, of course, it will search just about everyone else.
http://armorgames/user/(insert name here) is the best way to do it because google doesn't have me on it I always type in RescuePal and it doesn't come up!
