Albion forward Brennan Dickenson has joined Gillingham on a two-year contract for an undisclosed fee.
Dickenson has teamed up with the Seagulls' former landlords from Kent after two-and-a-half years in Sussex without making a first team appearance.
The versatile 21-year-old was bought by Albion from Dorchester Town in January 2012.
He failed to make a first team breakthrough and was loaned out to Chesterfield, AFC Wimbledon and Northampton during his time at the Amex.
Dickenson will now be playing under former Albion boss Peter Taylor at the Priestfield Stadium.
