Option to change the category that embedded comments go to

This can be done. The blog comment discussions get created in whichever category has its external ID set to embedded_comments.

If you created a blog comments Talkyard site, there'll be just one category, named Blog Comments, and with its external ID set to embedded_comments. But you cannot see it — by default, categories are hidden, when you create a blog comments site. But if you enable forum features (in the Features settings page, see below), and thereafter create a General category, then, the blog comment will still get created in the Blog Comments category and things should work like you want.

If you created a forum, (which you did, if you can see any categories, which seems to be the case, since you mentioned the General category)
then, you can enable the API in the admin area, and then create a Blog Comments category yourself, and give it the embedded_comment external ID — as folllows:

1. Go to the Features settings page: Click your username to the upper right, then click Admin, then, in the menu to the left, click Features. (Here's a URL: https:// talkyard /-/admin/settings/features )

2. Tick the Enable API checkbox, then Save at the bottom (otherwise the External ID setting won't appear).

3. Go to the categories page: https:// talkyard /categories

4. Click Create Category.

5. At the bottom of the new category dialog, click External ID (optional): None, and copy-paste: embedded_comments. Click Create, to create the category.

6. (I forgot) Edit the embedding HTML code in your blog: Add: data-category="extid:embedded_comments" so it looks like:

   <div class="talkyard-comments" ... data-category="extid:embedded_comments" />
   

Now, discussions for new blog posts, should get created in that embedded comments category.

Please let me know how it goes?
