Rightio, ill help you out a little
To become official, you will need members. 9 will not be enough. I would suggest making you the creator of the clan (basically you have final say), another 8 co-leaders and everyone else just monions or something. This way you wil be leader, you will have your co-leader(s) and the other various members
To get the TC for officialness, make everyone in your clan fork over at least 100TC each week. This is not a huge ask, but the cash will build up over time. To earn extra TC, enter tourneys, there are multiple 24 hour running tourney servers
KEEP YOUR MEMBERS ACTIVE! I cannot stress this enough, once members start becoming inactive, your over. It is extremely difficult to come back from it and usually you wind up being a dead clan. To do this, host regular clan tourneys.
Get some allies. If you have any TB friends in other clans then ask their clan to be allies with yours. Just post on their forums. An upside to this is you may one day merge. Another upside is the clan yourneys - Clan Nine vs their clan. Great fun
Make all members who wish to join simple minions / lower class members (as in not leaders / co-leaders). Once they have proven their dedication, have them fill out a form and promote them to a co-leader (lustfullness, limbo, etc.) position
Create a blacklist. This is where you display all members who you and your members will not allow into the clan. These can be people who have scammed you or your members, flammed, left (on bad circumstances) or have simply been banned from the clan. You can also add clas to this list
Make a clan video. Once you have enough members, get them to post their best replays and make a clan video. Make sure its something original that advertises your clan, not just some random clips. It has to be in sync with the audio (as in if the drum goes bang on the song, try to have a player landing a hit), it has to have a range of members, it has to show the players names (just in subtitles during the first few seconds of each replay), and it hs to have your clan name somewhere in it.
And that should just about do it. You dont have to follow anything that ive said, but I have been through this, I have made a clan and I have picked up a few things along the way.
