If you would like to write and article, you can write it in Word Document or a pdf file and then upload it to your post. Or, you can write it and copy and paste it into a post window as a New Topic.
To add uploads, open a New Topic, enter a subject line. Then add text in the message body of the post. After that, scroll down and you will see a tab for Upload Attachments. Click on that, browse your computer for the attachment, upload it, add comments or title for it and then click save attachment, otherwise it will not attach.
After that is completed, click submit. It is always best to keep the file sizes and photo sizes small, under 250 KB. If you have any problems posting the article, feel free to contact me directly at pilotsnpaws @ gmailcom and I will help you or post it for you.
