In this forum, there is a possibility to add a blog as a guest blog (in some areas) and we have to contact the forum owner and fill up a form and then wait for contact and in case have been approved, send over the blog post and it will be published.
I believe this process could be done entirely in this platform like the following.
1) User will visit a page and request to be a Guest Blogger and sign-in to the website
2) Select available area for Guest blog
3) Complete the part for abstract and briefly explain what it would be about
4) Submit the request
5) Then someone from Microsoft will approve/reject it and if it has been approved send a notification to user
6) User will login and have an area to write the blog and publish it
7) After click on the publish, it will send to the Microsoft and after it has been approved, the website will be published as a guest blog under the user id.
The above process will improve the Guest Blog posting experience and it remains entirely inside this platform
