Read. That's the best advice I can give you.

Read threads in different areas of this forum, not just spammy megathreads, look for substance.

Check out bitcoin wiki, there is some pretty good stuff there. Use google you can find everything you want to know with the click of a few buttons.

Don't focus on your rank; if you put in the effort you will be able to contribute to the forum and then you will begin to rank up.

And before posting anywhere else read the stickied posts at the top of the section, there is useful information there.
