I often point to the same demos over and over again. Since I cannot search for posts that have attachments, I'm left with my poor memory to find the appropriate demo file. I miss Comment's blog page. Can we create something similar?

well anyone can create a blog for them self on each thread / post there is a "blog" this button that will allow you to create a blog post - so you could link back to the original post. (you could choose not to publish them.)
