Yep there sure is! Click on your account username in the top right corner of the screen to go to your dashboard homepage. In the sidebar under "Blog" you will see a link that says "Submissions". From there you can submit an article for publishing on the front page.
You will need "Submission Credits" first before you can submit anything. To do this, you will need to own some LTBcoin first (if you ask nicely I will gladly send you some :) ), 1000 LTBcoin = 1 blog article. Once you have a few credits you can access the "New Submission" button and start writing your post, choose categories and publishing time etc. and when your article is complete, you can change the post status to "Ready for Review" to notify our editors to take a look at it. Feel free to submit your article in "Draft" status until you feel that it's ready.
You can also invite contributors to your article, and may receive contributor requests from our editors if they would like to make changes to the submission. Once you feel the article is complete and ready to be go, change status to "Finished", and combined with editorial approval (each category you select must be approved), your article will be published! PS: Don't forget to include a 400x400 cover image for the front page.
