Sign in and make an impression (8)

I believe the answer is:

I believe this is a double definition.

'sign in' is the first definition.
(thesaurus)

'make an impression' is the second definition.
(I've seen this before)

'and' is the link.

(Other definitions for register that I've seen before include "a manner of speaking" , "Class roll" , "Log" , "Notice < book" , "Offical roll of names" .)

I've seen this clue in The Globe and Mail.
