How can i move a post to another category?

A post can also be assigned to one or more threads at a later date.
To do this, log in and select your post in the Dashboard under 'Posts' and click the 'Edit' button in the list. Alternatively, you can navigate directly to the post page and click the 'Edit' link.

In the 'Topics' box you can select up to four main topics for the article. Finally, save the article using the Save or Save As button (below the article). The article will immediately be assigned to the new topics.
