If you want to group up to learn DB rather than set up a team to do a project then you're best off posting here on particular coding issues rather than asking to form a team.
The forum should be used more for a 'can anyone help me solve this problem?' or 'can anyone suggest a solution to . . .' rather than 'does anyone want to help me write a game/project?'
If you're having problems break it down into 'can anyone help me: set up a HUD, manage inventory items, track npc movement, etc, etc.'
Like-minded people will see your post and help.
