@glenalbrethsen noted bro. I will remind everything you said to me. So i think i misinterpret @abh12345 post. Very useful information.

find your the few tags that you know might have some expertise in, and try to build a following. And in addition to that, it's a good idea to leave clear and thoughtful comments on other people's posts about what they're talking about so people know you're around.

Thanks Dear for helping me.
