# requestCoverage

Ask for coverage of places ("Cook County, IL"; a county keys to its cell, anything else comes back in gaps) for signals by name (signals, always sent: [] when asking by family), or families picked outright (FORECLOSURE, PREFORECLOSURE, PROBATE, PREPROBATE, TAX_DELINQUENCY, CODE_VIOLATION). For those six, read listMyCoverageRequests first: one already asked is not asked again. Any other signal (liens, evictions) is recorded and reaches sales, but no read returns it: ask it once and give no date. Any member.
