I would highly recommend getting familiar with Sythe as a website & as a community first before you do anything else. Read the rules and make sure you understand them completely. Then I would check out the market section and read some guides & informative stickies in that section to familiarize yourself with different types of trading procedures, how to safe safe & document your transactions (everything should be filmed or screenshotted, and then neatly organized in a file folder somewhere on your computer).
Learn what kinds of scams are common and how to avoid them, and all the things you can do to stay safe and protect yourself. Also, learn the different ranks around Sythe, and learn how to use your discretion to decided who is trustworthy and who is not. Things such as a fancy UI & signature, high post count, early join date etc. mean absolutely nothing when terms with a level of trust.
Lastly, you should begin trading with other users and become immersed in the community. Meet people, make friends, try to help people out where you can, and explore the site and try to get involved in whatever interests you, and get your foot in the door to the markets you are interested in.
Building a reputation for yourself and gaining trust doesn't happen over night. It takes time and effort, but it will happen sooner than you think if you remain active and helpful within the community. There are lots of people here willing to help you learn the ropes, and there are tons and tons of great guides and/or informative posts that will help you learn everything you need to know.
Good luck my friend, and if you need any help don't hesitate to toss me a PM
