Be specific when recruiting. What do you have to offer? What are the benefits of joining your guild? Why should they join you guild when there other guild out there recruiting? Are you an honest leader or do you just want players to become guild members?
These questions will eventually be asked by players and you'll have to give them a reasonable response, it's one thing to get players to join it's another thing to get them to stay. Remember players can leave as fast as they join and before you know it you're back at square one.... don't come on to strong, be patient, and think carefully. Good luck, wish you a prosperous guild
