Before survey info on the start, there was something like "invite your friends to PWO". 1st I want to ask is PWO inviting our friends? You should send mails to people: After long downtime we lost some players, after problems like that you should inform players that game is back. Last time when game was down for so long, there was a rumor that pwo is closed forever, many players never came back. Info about events, it might bring people back. To inactive players lets say after 1 year, 1,5 year - month, week and one day before deleting account. Also you can give them some little awards for people who came back after long time (tokens, ms), maybe they will stay with us longer.
2nd You can make some system of rewards for people who are inviting others, for example 1 token for someone who invited 5 people that played 50 hours.
