There have been a fair number of new folks checking out Marriott Rewards Insiders (MRI) lately. Some come to post a comment on the latest sweepstakes topic. Others come to learn about promotions like the MegaBonus. Still others find their way to MRI to read up on travel topic, post a question, or try to resolve a customer service issue.
Many get here and aren't sure what the purpose of the site really is. So this question goes out to long-time Insiders (though those who have joined more recently are also encouraged to add their thoughts).
How would you describe MRI to someone who is thinking about joining (or someone who has just joined) this community?
