I have bots running in #latex and #context that allows users to test LaTeX, MetaPost, and ConTeXt code in real time and have a URL generated for the output of their code (or a log file of the compilation process if their code fails to compile).  I also keep logs of these rooms, and these logs can be searchable.  I could easily make my logs available for the website if it is deemed appropriate.<br>
