Letters in the sand is a event in Sorority Life on the On Campus tab on the Socialize tab. You get 6 letters and you have to make words out of those letters. If you find the six-letter word you'll get a 30 sec time bonus. There are some sites that will help you solve more anagrams. I like this one: http://www.specialist-online-dictionary.com/word-unscrambler.html , it finds lots of results very quick and it gives you 3,4,5 and 6 letter results,most of the anagram sites only give you one result so I really like this one. Hope I helped you.
