Publish on Tumblr with an easy-to-type email

MathJax is now available through a CDN, so you don't have to install it on a server any more. All you need to do is include a few lines in your html header and you can start using mathematics in your posts.

To do this, go to Theme -> Use custom HTML, and insert the following just above the </head> marker:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js"></script>

Save changes, and you're ready to include mathematics on your Tumblr pages. Try, for example

\[ \exp(x) = \sum_{n=1}^{\infty} \frac{x^n}{n!} \]

Good luck, hope this helps.

Reblog is mainly for re-posting blogs by others;

http://www.tumblr.com/docs/en/dashboard

Reblogging lets you quickly share things you find on Tumblr. Clicking the Reblog button next to any post will create a copy on your blog, and give you a chance to include your own comments.

Reblogged posts automatically include attribution to the original poster.

But you can reblog yourself by doing the following;

http://tumblring.net/how-to-reblog-yourself-on-tumblr/

1. Right Click on the following bookmarklet link – REBLOG YOUR OWN POST ON TUMBLR – and choose “Bookmark this link”

2. Now, once you are on one of the posts of yours that you want to reblog (not the dashboard, but the article itself ) Click on the Reblogging bookmark you just saved and you will be taken to the reblogging edition screen.

The bookmarklet mentioned above is;

javascript:%28function%28%29%7Bwindow.location=%22http://tmv.proto.jp/reblog.php?post_url=%22%20window.location%7D%28%29%29;

Hope this helps
