Just out of curiosity, I set up a Nabble forum. Simple setup, appears to work nicely. Don't have an immediate need, but was playing with a site with one variant. I wanted to have a copy of the Nabble widget on the narrower variant, so tried to "share with variants" but got message stating that's not possible, just do a copy. Tried that, and the copy was same width used on my main page (540 pix), so I modified the width to 374 to fit within the column I'd allocated on the variant. It looks fine in design mode, but in preview, the copy just shows "loading" and it never displays the forum on the narrow page. I set the widget back to full width, just to see if the narrower display was the problem, and it still showed the "loading message" and never displayed the form.

Has anyone played with this, using a Nabble form on a main and variant, and gotten it to work on both?

Thanks!
Ken
