Whatever you plan to do with your blog in the future, please make sure it stays public until you get your final grade from the university. I need to be able to access it to complete your final grades.
After that, here are some options…
1. Keep at as a public sample of your work.
If you are proud of what you have accomplished, you can link to your blog or to specific posts for internship and job applications.
2. Edit your blog so only your best posts are public.
If you are proud of your blog, but don’t necessarily want everyone to see everything you have done, you can go back and hide some of your posts. Edit an individual post. Click on “Visibility.” Change an individual post from “Public” to “Private.”
3. Make your entire blog private.
Setting your entire blog to private will allow you to save your work, but others won’t be able to read it without a password. Follow the instructions for Making Your Blog Private.
4. Delete your blog.
If you are sure you want to get rid of your blog, you can delete it. Here are instructions for how to delete your blog. If you delete a blog you will not be able to get it back. So don’t delete it until you are absolutely sure you want to eliminate your entire blog. In a month or so, references to your blog should drop out of search results.
5. Continue your blog.
You may want to continue your blog in your own way. Give yourself assignments. Grow your audience. Make your blog what you want it to be.
6. Upgrade your blog.
If you want to spend some money to upgrade your blog, WordPress.com gives you a bunch of options such as registering a domain name, getting rid of ads, the ability upload audio and video directly, etc. Carefully research the options before you spend the money.
Or I suggest you move your blog to your own web host (costs about $5 to $7 a month) and use WordPress.org — that’s .ORG — which is different from WordPress.com. This is a good option if you want the experience of building/modifying a website. You can learn more about HTML, CSS, etc.(See What’s the difference between WordPress.com and WordPress.org)
