The first is found at the StarBattles forum.
The Forum adds::
1) a means for playes to post directly onto the website,
2) screenshots and stories for fun reading,
3) orginial maps for download, and
4) a place to meet friends and fellow Starcraft:Broodwars players.
This Forum is NOT for chatting, though game related subjects and questions may be posted. Games are "open", meaning, they can be played on any map, with any other player(s), or single player. Anyone, regardless of other clan affiliations, may post (after adding their name, and some info to the "Join" folder).
The second is with organized Team play.
Clan members are divided into "teams" for multiplayer games with others in the clan. Team members may battle with others on their team, in order to form better attack strategies, and just for fun. Teams members can also battle members of opposing teams. Wins and losses are emailed to wizkat@email.com so that the "season records" can be recorded. To join these teams, or clans, one must send their name (and preferred team) through the Join form.
Team members can NOT change teams after joining UNLESS another team is willing to offer one of their players in trade, or some other "buy off" that the members team accepts. Even if the player does not wish to switch, this is a contract sport, and the team has the finally say. Players may object if they have good reason, however, and complain to the board (KittieKatt and Gone'Postal).
