Stick notice on front of present (6)
I believe the answer is:
adhere
'stick' is the definition.
(to adhere to something is to stick to it)
'notice on front of present' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'on front of' says to put letters next to each other.
'present' becomes 'here' (both can mean in attendance).
'ad'+'here'='ADHERE'
(Other definitions for adhere that I've seen before include "Stick fast (to something)" , "Stick to as by suction" , "Stay attached" , "Stick to or remain faithful" , "Stick to, cling" .)
