Welcome to the community!
You can visit the pinned post in every thread so you can get an idea what are the things you need to deal with, we recommend I guess to start with the Beginners & help added with the Meta board so you have an idea what the basic knowledge you must to learn in the forum. Ideal to visit your local board too so you can also guide them easily in your native language at the same time, also whats your reason why you join in the forum so we can recommend a board that is suitable on the things you are interested in.
