I'm seeing that mostly you post in the Teens and YA forums. Neither of these are heavily read or used. So part of the problem here on CC may be that you're posting in sections of the site that do not receive a lot of traffic.
But i also see, by looking through your posting history, that you do get responses. Maybe not a lot, but you do get them. Perhaps it's better to focus on the responses that you get instead of focusing on the ones you don't.
Lastly, by posting in sections that are not busy, this means people will not be engaging in many conversations in these areas. It may benefit you to try other areas of the site, look for threads that are active and try to include yourself that way.
You haven't really posted very much, either. 34 posts in 9 months is a small amount. Therefore, if you want to be noticed more here..
-pick areas of the forums that are used more
-post in threads that are active
-become more active in your own posting
-focus more on the replies you get instead of feeling you don't get enough responses
It takes time to get into groups online. Unless you are a boisterous personality, which i can tell you are not. But in that time you have to be active. Posting more than once or twice a day. Also, one thread you started i saw no title, therefore no title to click on. There was a work around, but not all people may figure out how to view it anyways. So that didn't help any.
