Where do my posts/responses go?

Hi DU community! I have been reading the contributions to this forum for a decade, but rarely post. However, I have tried to actively participate more recently, and I always forget to put a subject line because I’m just usually responding. Once I hit “post” and then realized I needed to subject it, the entire draft is gone or at least I can’t find it.

I work really hard on my posts and it’s incredibly frustrating that I cannot find them anywhere, so I’m hoping that you more experienced DUers can show me the way.
