The default find member function has a restriction which limits the results to only those members which have been active within the last 180 days, this add-on eliminates this limit so if you're searching for a member which has been inactive for a long time, you can still find the member.
(Example of Find member block under Members tab)
- Download Andy-FindMember-1.1.zip and unzip it.
