When posting work online on a website such as The Young Writers Society, it is important for you to understand these tips and pieces of advice.
Constructive Criticism Edit
You have to learn to not get mad when someone gives you constructive criticism. Not everyone is going to love your work, and even if they do, but all they say is "This is great! I love it!", it isn't going to help you improve your writing style.
Quid Pro Quo Edit
Many writing forums require you to review the works of others before you submit your own, and/or to keep a certain ratio of reviews to submissions. Even if the forum does not, it is still a good idea, since it will make you more visible and will draw more people to your own work.
