That means you’re using standard WordPress. So you won’t see a link to blogs.

If you set up your new users with the role of “contributor” or higher, they can post.
Login to the WP backend and navigate to “Settings > General” and select “Contributor”.

Then download a plugin like:

Posthaste:
https://wordpress.org/extend/plugins/posthaste/

or Quick Post Widget:
https://wordpress.org/extend/plugins/quick-post-widget/

Also please refrain from bumping your own post every hour. Bumping your thread every 24 hours is enough.
