For all the Realtors out there, Erick Del Orbe at HAR taught me how to put a twitter and facebook button on my HAR website. Here are the directions. And if you have problems, please contact HAR as I don't know the ends and outs to help further. 

For Twitter you can go to http://twitter.com/goodies/buttonsafter you login to twitter you'll have a couple of different buttons to choose from. Once you click on a button it will give you code that you can put on your HAR profile  (log into to HAR and the left maring note the MLS tool.  Uunder that click "member website". then click "add new profile" and paste the link. Now the Twitter button appear. 

For facebook you can go to http://www.facebook.com/facebook-widgets/index.php once you login and you'll have different types of badges that you'll be able to add to your profile.  If you have a fan page, I recommend adding this one: http://www.facebook.com/facebook-widgets/pagebadges.php . Click on the icon that says "other" and copy the link. Then paste it in your HAR profile (log into to HAR and the left maring note the MLS tool. under that click "member website". then click "add new profile" and paste the link) . Now the Facebook button appear.
