how to remove the height restriction on an embedded forum on the blog.
The height restriction that you see when embedding a Nabble forum in another web site is almost always caused by the wrong options being selected for the area of the page in which the forum is embedded.
Many users of Weebly, Wix and Blogger seem to have this problem. If you use one of these to build your main site check the service's Help pages to see how to avoid limiting the height of the area you make for the forum.
Volunteer Helper - but recommending that users move off the platform!
Once the admin for GregHelp now deleted.
