Forms that save to the database

I’d like to create a wordpress site which enables users to contribute content, let’s say jokes for example, which will then be moderated and if approved will be shown on the site. I also want ratings to be available for these jokes. The ratings feature can probably be handled by g star ratings but I’m still looking for a good solution for the main process of letting users contribute the jokes. I’m thinking it could be like a form that would save to the wp database so i could then fetch these jokes and categorise them etc. Any advice on what plugins could be helpful for this? thanks
