The form is the whole way in, and writing it yourself is enough. The market around us usually wants a network in place before it reads anything, and that is the cost we remove.
Every application is read by a person here, all the way through, and the decision is made by the people who read it. The answer you get is written by a person, to you.
Write plainly rather than polished. What you are building, who it is for, where you stand right now and what is difficult. A straight half page tells us more than five polished ones.
If the answer is no, you are welcome to apply again. A no applies to that application at that point in time. Companies move, and next time we read from the beginning.
