Online forum host CrowdGather added a website for aviation, rail and watercraft model hobbyists to its offerings. The 33,000 enthusiasts with Zealot.com join the hobby segment of Woodland Hills-based CrowdGather’s network of special interest forums and message board communities. CrowdGather also offers forums in technology, automotive, home and family, travel and entertainment, and sports and fitness among others. The company is always looking to acquire forums or to help forum owners manage and monetize their communities and the Zealot.com members complement the rest of the CrowdGather network, said Chairman and CEO Sanjay Sabnani.
