发现一个好玩的东西：Hacker Spring，可以看作是一个只能用邮件发贴的论坛，无需注册、登录。

​

最基本的用法：邮件发送到“*@hackerspring.com”即可, *代表主题名称或子论坛，邮件标题就是你帖子的标题，邮件正文就是你帖子的正文。如发送邮件到httpsmail@hackerspring.com，就会收到一封“Your E-mail was received”邮件发送成功的邮件，打开Hacker Spring网站，点击“New”就看到自己新建的帖子，如下图：

点击帖子下方的“Leave a comment”就可以直接回帖了，当然也是通过邮件发送的方式。目前网站已经创建的主题或子论坛不多，主题创建及发贴没有任何限制。

​

其它用法

1. 删除帖子

   找到你发送的那封邮件，点击回复，在邮件正文中填写

   $DELETEME

   就可以顺利删除了，删除成功后也会收到一封邮件主题为“Your E-mail was received [Re: *]”的邮件提示你“Your E-mail was deleted.”

2. 添加附件、链接等

   How do I work with a Javascript or CSS file?

   Include the JavaScript or CSS file as an attachment. Then, in the body of your e-mail, use special commands to include.

   To include a Javascript:

   $SCRIPT(filename.js)

   To include a CSS:

   $CSS(filename.css)

   If you’re including a CSS or JavaScript file in your html files, just use normal HTML.

   How do I make my attached index.html the first page that shows up instead of an email?

   To redirect to an HTML File put this in the body of your email:

   $REDIRECT(index.html)

   You can also do forum style link-sharing by simply doing:

   $REDIRECT(https://hackerspring.com)

   Don’t forget to strip the text formatting, but we try to do it for you if you forget.

   How do I link to an attachment HTML file?

   To link to an HTML File:

   $LINK(filename.html)

   Or with link text:

   $LINK(filename.html)[Anchor Text]

   This is strictly just for linking to attachments. Use your e-mail provider’s link function to link to external websites.
