Kurtis Guthrie joined Colchester in the summer of 2016 for an undisclosed fee.
Kurtis joins us from the Conference National side on a two year contract, after putting pen to paper on Tuesday afternoon.
Kurtis enjoyed a productive season with Forest Green in 2015/16, as they just missed out on automatic promotion to the Football League before losing in the play-offs.
The 23-year-old scored 12 goals last season, playing both through the middle and out wide.
His form saw him selected for England C in March, as he scored against Ukraine.
The Jersey born forward started out with Accrington Stanley, before progressing well in non-league over the last few years.
