Thanks for the update lcipriani.
Is the plan to eventually make all of the website content editable by the same sort of system as the Language Reference? I know this is planned for the library reference pages, but I'm asking about the rest of the content. That would be great. I'm really enjoying being able to submit pull requests to the reference-en repository. The old system of submitting issue reports was very inefficient both for me and the person on the Arduino team implementing the suggested changes.
I'm also glad to hear about the search engine. Just yesterday I spent a lot of time with a Google search for an old thread. I knew the exact keywords that existed in a reply I had made but it didn't show up in the results. I ended up just scrolling back through tons of my replies to find it.
