Explanation of name

First of all, an apology to readers who have suffered or had loved ones suffer through tick-borne illnesses, such as Lyme disease or Rocky Mountain spotted fever. The name comes from a common term in accounting firms, particularly those in auditing, which use the phrase "tick mark" to describe a standardized symbol indicating that a particular procedure, such as "footing" (adding a string of numbers) or "vouching" (looking up and in some cases examining a document) has been completed.
