### Fighting spam

Comment author must now have a previously approved comment. This will slow down commenting if it is your first comment, but will stop spam from appearing.

### +1

Saturday, July 16th, 2011

If you like this post click the +1 icon.

(The WordPress plugin is called ‘Plus one’. Details here.)

If you are on Google+ the pages you click +1 for will automatically appear in your profile’s +1 section. Which means it is also a way to bookmark pages for reading later.

### Latex is now accepted in comments

Tuesday, April 5th, 2011

Now LaTex works. I just added a plugin called WP Latex. Note: LaTex does not work in the comment preview, but it does show in the comment when it is submitted.

The plugin converts inline latex code into PNG images that are displayed in your blog posts and comments. Use either [xxxlatex]e^{\i \pi} + 1 = 0[/latex] or $xxxlatex e^{\i \pi} + 1 = 0$ syntax.

Where xxxlatex should be replaced by ‘latex’ without the quote.

• $e^{\i \pi} + 1 = 0$
• $\frac{\frac{1}{x}+\frac{1}{y}}{y-z}$

Now, who can suggest a simple tutorial for basic math notation?

Update 25.01.2012:
http://www.codecogs.com/latex/eqneditor.php lets you preview your LaTex so you can see that it is OK before you use it in a comment. Link thanks to Richard Sabey.
