Ok, I know this is basic to many, but I did get an email asking how to do this. Posting on forums may be something totally unfamiliar to those justing starting out with computers. So, here's how to do it.
To post a question on the forum:
1. Navigate to the most appropriate board (i.e. freshwater, beginners, aquarium nitrogen cycle, etc.) for your question. Putting your question in the most appropriate board helps you to get a quicker response and also helps others that may have that same question find it easily.
For example, if I had a betta question, I'd go to the main forum page and scroll down to get to the freshwater section and then I'd look under the freshwater fish species section for the betta board and click on that to open the betta board.
2. Once inside the appropriate board, click on the "New Thread" icon, which looks like this:
3. A new page loads that lets you type in a TITLE for your message and there is also a big box where you type in your message/question.
4. When you're finished typing your message, click on the "Submit New Thread" button below the posting box.
That's it! Welcome to the addictive world of forums! Muuahhhaahaaha
Note: Replying to a post is a similar process. There should be a quick reply box at the bottom of each topic. Type in your message and click submit. Or, you can also reply by clicking on the "Post Reply" image inside each topic. It looks like this:

. After clicking on that button you will load a page that is very similar to the new thread page. Type in your message and submit.
