The ARRL is a useful site for up to date information on happenings regarding rule changes and so forth. Visit the site and judge for yourself. This is  a national organization, requiring membership for the magazine.   ARRL QRZ.com is a very informative site that hosts a swap page, and also practice tests for upgrading,. They also have other forums that you may enjoy. This is a free site, and I visit it frequently.   QRZ Eham is another site that I enjoy visiting because of its various forums and articles. They also have a swap page, and various forums that gives a lot of useful information to the beginner as well as the seasoned hams.  EHAM This is one neat site as far as I am concerned. It has on the average over 200 new ads daily, as well as being able to search certain criteria. They also have forums here. You will find a lot of fair sellers here, no ebay stuff.  QTH Her is a site that is of interest to many hams interested in APRS. You may find a station running aprs tracking stations or just their home station. My wife and I use it frequently to track friends or for her to keep track of me in the 18 wheeler. APRS
