If you are being allowed into the forums but you are not able to post, then you are perhaps trying to post a Forum Container rather than a Topic. This is a common error that we are trying to figure out how to prevent:-) Sorry...growing pains...But the answer is simple!
When you are in a Category, Family and Parenting, for example, and you first click into it you are taken to the Main Topic Level. Those are called the Subtopics. You have to click into the Subtopic where you believe your post belongs, then you can create topics;-)
In the top menu, click Women's Forum - This will bring you to the front page of the Forums, indicating how many new messages are in each category and who posted the last message.
When you are viewing a post in the Forum, you may post a reply by clicking "Reply", which is located in the bottom right corner of each post. Type your reply and hit Preview. IT IS VERY IMPORTANT that you THEN CLICK SUBMIT or the post will be lost.
