I Need Help Navigating The Forum!

For the first question, I use the Tools button (right below the top banner ad), then My Topics. This will list all your posts within a specific time frame and the latest response and date.

For the second question, it's just a flat discussion thread. You don't really reply to a specific post. A couple things I have seen people do:

Use @Kenkat to indicate you are replying to a specific poster

Use the quote function. Copy the text you want to refer to and put it in quote tags using the Page with the Red Arrow button in the format line. You can only do this if you use Full Reply, not Quick Reply.

I just click on my user name in the upper right corner on every page. It brings me to my profile page. From there in the first left column you will see a tab that says 'view unarchived posts'. Click on that to get their the long way and view your recent posts.
Or the easiest way is just to the enter the site via the 'new posts' page. From there, you get an overview of all new posts in every section and can easily see your post assuming it was posted in the last three days or so. That Is the way I enter CCF. I just save it on my browser. Here is the URL: https://www.coincommunity.com/forum/active.asp
