I think you can help out by reading everyone's posts and trying to help and support people within the forum. This is a great community and helping people rise and figure out new things is the best way to help it grow in my opinion. Who knows, in a year or two this place could be bigger than bitcointalk forums too, or at the very least comparable. I try to post a little bit every day to try and help out but I'm a bit of a novice in the crypto world still. Having a conversation with people will lead to learning more as well, there's no really wrong way to go about it, just don't spam nonsense. Some people help out by posting news articles and other things too, you can try that as well. Or maybe posting how-to guides for specific crypto topics. The sky is the limit.
