Cooperation of LaTeX-Community.org and writeLaTeX.com
Since today, LaTeX-Community.org readers can use an online LaTeX compiler in the forum, provided by writeLaTeX.com, an online collaborative LaTeX editor with integrated rapid preview.
By a single click on a link above a code box, the reader will land in the editor which shows the code on the left side, and the output preview on the right side. Compilation is done in realtime.
Now it’s easier to support LaTeX users, especially if they would add a compilable minimal example to their problem. Even small code snippets would be wrapped to create a basic LaTeX document.
For more information and examples, have a look at the announcement.
