I'm Longsyn, and I'm looking foward to contributing to the site! I'm a friendly girl when you get to know me, and I hope you do.
Nice to meet you, Longsyn! I hope you enjoy your time here on the site. Since you say you're planning on contributing, make sure you set up a single sandbox page devoted to all of your future work, such as any drafts of SCPs you're working on. Once you feel you're finished, go ahead and present that draft to either the draft section of the forum or the chat for critique on it. The latter will usually get you a quicker response, but the former tends to come with more in-depth review. This is a pretty critical part to writing anything for the site - especially if you're new - as articles tend to tank hard without any sort of peer review. The chat's also a good place to hang around in general. It gives you the opportunity to interact with your fellow members, and most of us there are pretty friendly.
Now that that's out of the way, good luck in your future endeavors here! I hope you come up with some really great ideas, and it's always nice to have more regular faces around the forums and article discussions. If you need any further assistance, such as for critique on a draft, feel free to PM me. I'd be more than willing to help in any way that I can.
