I did the same ... lurked for years and found help when I needed it.
Great to have you join the 420mag community. Like IB said - you likely already know your way around ok. There's some good help threads, plenty of great grow journals full of Cannabis eye candy, and a high proportion of super nice folk ready to help you get your growing kung fu honed - if you're after that.
Are you growing? Having your own journal is a great way to get assistance and get to know folk.
It's great 'round here. If you need anything you can't find, please ask!
