SMRT is a part of SC Swimming, which has a great parent info page. You'll get lots of helpful tips about swimming, including the role of the parent vs. the role of the coach and the 10 Commandments for Swim Parents.
The USA Swimming website is a fantastic resource! You'll find great articles, tips, and all kinds of information there, and if you sign your swimmer up for My Deck Pass, he or she can earn patches with each competition. You can easily look up times for USA Swimming members with Individual Times Search, and you can see the fastest times by event and age group in the LSC, zone, or country with the Event Rank Search.
