okay, I delved into this deeper. Ang, your tab on your blogspot page for your forum is a direct link to the forum, not they page. This is not correct. You should create the page where the tab linked to your blogspot page. Then on the blogspot page, put the embbed nabble code in the html.
I cannot get my forum to show on my blogger blog page. I copy and paste the code into a 'new post' on the blog and I just get the name of the forum with the blogger's comment box. Do I need to post a message in Nabble first?
I am sure I must be doing something silly but am completely stuck - HELP!!!
