Just so you realise the two comments above are sarcasm. The idea of the forums feedback is to give you crit on ideas you come up with not come up with the ideas for you!! Good luck and let us know when you've came up with something you are looking for crit on!
Guys, if you've got nothing useful to add please refrain from replying with saracstic replies, this is meant to be a helpful community as Jamie says, and threads with replies like this will only put people off posting and getting involved on the forums!!!!
