Man, this has been long overdue… better late then never though!
There is a new CSV import utility for blog! You can access the new import utility at {{yourdomain.com}}rw_common/plugins/stacks/total-cms/totalimport.php
When you visit this page, there is a download link to a sample CSV file. This import utility will not import any images. It will only import the blog post text data. If you need images in a blog post, you will need to upload that image via the Total CMS blog admin form once the import has been completed.
