I don't subscribe to their service. Read into that what you wish. :)
The method used to convey your rights (Probate order of distribution, executors deed, trustees deed, etc) should have been recorded in the county clerks office for each county in which there is property. If that address (or name) is no longer current, it is best to file an affidavit of ownership stating your previous name, current name, and address along with the description of the properties in that county. This should be filed again if you move.
While we always want to be contacted when someone is interested in leasing, you really want to avoid is being identified as a missing mineral owner and force pooled without your knowledge.
Having the information filed of record with the county clerk "should" be adequate defense in an unfair forced pooling default election.
