What website can aspiring screenwritters create profiles and upload their scripts?

[Something Blue]

The ONLY legit website that could lead to something, the ONLY website that managers, producers, etc. go to find worthy material is the Black List. You get your screenplay reviewed, and if it gets a high enough score, they make sure people see it. Their standard is extremely high, they demand a professional level. And that's what managers and producers look for too.

If you want something that leads to nothing, you could try at Simply Scripts.You also got InkTip, but since they don't have the filtering system the Black List has and anyone can upload their material, decision makers don't really look at what people upload. You could also pay to have your logline appear on their newsletter. But once again, that doesn't lead to anything, almost never.

If you think your screenplay is amazing, submit it to the Black List and see what happens. If your score isn't high enough, either your script isn't ready or isn't good enough. The Black List is your real test. And if you and the script really are amazing, doors might open for you.
