To join an existing coalition you have to follow the private link of this coalition. You get this link from an existing member or the manager of this coalition.
Once that you've followed the link and used the button "Join this coalition" just follow the simple steps and in seconds your account will be created. Subsequently one administrator of your alliance or the coalition manager will activate your account before you can have access.
Each coalition has its own private space and the list of coalitions is not available for obvious security reasons.
