Unity 7 Distribution List Usage

[petrojosh]

Is there a way to find out when a distribution list was last used in Unity 4 or 7? We are upgrating and would like to know whether or not to COBRAS out the DLs, some of which are quite large.

I am going to say no.  I have searched our internal db.  Reviewed the advanced settings and reports.  I dont see anything that would help.

Use of public lists is not tracked internally anywhere - there's no way to pull such data.
