1. You could have a new category named 'free talk' rather than this. This is kinda hidden! There people may post anything they like!
2. You could have a category named 'Suggestions', these are important for you in the future to have a good site and clan.
3. You could have a category named 'Screenshots'. There people can post to show you how well they played.
4. You could have a category named Clan Matches. This clan will be good and would like to play other clans! This way, you need somewhere to post the screenies of that! (this one isn't so vital).
