How do I post??? Help pls

Hi there! I'm very new to the message boards and I can easily figure out how to reply to people and how to post a new thread, but, for the life of me, I cannot figure out how to post a message within a current board (not a reply). Can someone help me?

I know it sounds so silly and I feel like it should be simple but I'm completely failing on this.

Any help is greatly appreciated! Thanks in advance!

Oh! I thought when you replied to one person it wouldn't be the same as replying just generally to the post! I've been going crazy trying to figure out another way to post. Thank you so much!

Also, it doesn't matter WHICH "reply" button you click. So, if you are replying to a specific post, it's better to use the quote button (but type your reply AFTER the closing quotation mark) or to mention the poster by name.
