Is a user a domain and you get to have 3 sitemaps on the tier 1 level?\u000aSo 3 users equal 3 sitemaps for 3 different domains?

Nope.\u000a1. we have ZERO limits on how many domains to crawl \u002D just a limit of how many TOTAL Pages *across ALL your crawls/projects.\u000a\u000a2. Users of your workspace have full access to all features across all projects.\u000aThey can crawl all they want.
