As a club director, what do I need to do for my club to be successful?

It's just like any other thing starting out. It also depends on your definition of "successful".  Is, in your opinion, success defined as winning every tournament?  Having a great time? Having friends play together? Playing volleyball, regardless of anything else?

The fact is that once you've decided on your measuring system, you need to decide what's required.  Here are some ideas that you might want to think about while working on your club or team:

Recruiting: Do you have the right players? Do you have enough people? Realize that people are going to drop/change/stop playing/get injured.  Some people will not make all the tournaments your club is going to.  You need to make sure you've got the players you need.

Website: Are you going to have a website? If so, what are you going to put on there? Are you going to just use it as a generic one page here's who we are? Do you want something more complex where you can track rosters, attendance, payments, etc? 

Tournaments: Does your club plan on playing in every tournament? Just the tournaments in your city? Regionals? Nationals?

Nationals: This merits a point of it's own.  Are you trying to put a team together to play at Nationals?  If so, you need to consider the cost involved (travel, tournament cost, hotels, foot, etc) so your team is aware. 

Multiple Teams: There are benefits to multiple teams in a single club, but it also adds the level of effort and paperwork required for the tournament director. Is it worth it to you? Do you have enough players?

Practices: Is your team going to have regular practices? If so, you need to find a place to practice.  Are you just going to join a league to practice such as the YMCA, Austin Recreation Center, etc? Then you need to join those organizations and join the leagues.

There's a lot to consider, but in my opinion, it's worth it.
