Best thing to do is try to keep the club as active as possible use the club forum and wgt chat to keep in contact with your members you could also look at other chat options maybe for a later date but start looking now there are plenty of options out there.
Keep posting tourney's try to recruit active players. daily players that have a good cd streak and use their pass daily will help your club to level up quicker, higher level club = more membership spots allocated for a bigger club, more available spots for directors, free shot pal, free putter pal and extra xp for members and club
