ActiveRain is a real estate blog community used by predominately Realtors but also other real estate professionals. They have a free sign up and also an upgraded plan that offers some SEO benefits (and other perks) for agents.
They have an active Q and A section with tips on handling ornery sellers to marketing, technology, social media, and lead generation,
Occasionally, they have webinars and they can provide excellent content on a variety of subjects to assist any Realtor.
You can find great content on the site from other Realtors. Also gives you ideas on what may work for you. If you blog and create any real estate content, ActiveRain can help. If you are looking to start it can help. If you simply looking to bounce an idea off of many agents, it can help there too.
At the very least sign up for the free plan and check out the site. Write an article or 2. Jump on the Q and A section and answer a few questions. My feeling is we can always learn something new. On ActiveRain, you have an enormous pool of agents to pull info, advice, and tips from at any time.
