New to devcentral

Hi Guys,

I am new to devcentral, and was trying to upload one the irule that I wrote recently. But it won't let me upload it, as its saying that I need to earn more reputation before I can add a snippet. Is there another way to contribute to community and share my irule. If not, how can I earn more reputation. Is there a doco which explain how I can use dev central. Sorry but I am little lost here, and need your help.

Regards, Gagan
