It doesn't matter if you responded to your own post. It will still appear in the thread and everyone will see it. All the other people who posted in the thread will automatically get an email alert (assuming they subscribe to forum email alerts) that there's a new post. And it should also be listed as a new post when the others in that thread click the bell icon at top right after logging in. The forum automatically monitors for spam attacks, so if you post the identical content more than once within a set time limit, the bot flags it as "spam", even though it was an unintentional issue.  And you're not limited to only one post per day, as long as it's not just the same content...    
I'm just amazed and frustrated by this community's  rules. It dosent make any sense.  someone responded to my post and I went to respond back. I mistakenly posted a response to my own post instead of the person who gave me an answer. So, I tried to post again to that person and get a message that I am flooding something within 30 seconds! All right, so I wait 2 minutes to post again and I get the flooding message again but now I'm posting more than one time in 3,600 seconds! This is crazy! I'm not trying to flood any conversations. Is a person only allowed to make one post per day?
