Where can I submit sketches?

I thought this would be a one stop shop for getting my comedy out to the masses, basically because I stupid. Now I really want to learn and try and get some stuff critqued by show runners et al. are there other places I should be looking? Am I just not seeing the opportunities here? As I am very new to all this pretty much any hints/tips will be helpful.

Google has proved less then helpful.

Have you tried searching the forums? There's plenty of old (and some new) threads detailing people, companies, competitions, etc that want sketch submissions.

Try looking at the Radio Rejects, Newsrevue and Treason Show threads for starters and have a look at the Newsjack page on the BBC website.

Thanks you, very helpful.
