Question for Any YouTube Vloggers Who Might Be Here

[Cumberbatch2012]

How do you promote your channels?  I share our daily videos everywhere I can think of, and we have gained subscribers, but I know we could do a lot better.  I have Googled for YouTube vlogger forums to join, but nothing much comes up.  I joined one and then was not able to post.  Weird.  There's a link to my channel in my signature, but if any of you know where I could post to promote the channel more, I'd really appreciate it.  Thanks!
