The Telligent blog posting is fairly simple at the moment. However in real life blog posts are not written and published by one person. The process for writing, editing, reviewing, etc. can involve multiple people. As a simple example the SME may email a post to the blog manager who adds it to the system.
Currently there no way to allow Person A to draft a post in Outlook/Word (i.e., outside of the platform) and forward to Person B for review and publishing so that it looks like Person A actually created and posted it.
