With the move to Verint from Jive, we lost the ability for blogs to exist in the 'location' of member accounts as a 'place' to post your blog.
Those who are a part of the Top Members have had a blog Verint section created for them in the Members area, this is a perk of being a recognised contributor to the element14 Community as a Top Member.
These are available here: Personal Blogs
Every other member's personal blog has been archived here: Legacy Personal Blogs
To contribute a blog post to the element14 Community, you must first choose a group for it to be posted in! You can do so either by using the drop down menu at the top of the website, or search for one and filter by 'groups'.
If you cannot find an appropriate Technologies or other topic for it to be relevant to, then you should be able to post it in the Members blog area here: /members-area/b/blog
