I am planning to do that. I already posted a request for suggestions what should go into that. Getting started guide for posting LAMMPS questions to MatSci.org
But I am currently too busy getting the stable release completed before the LAMMPS workshop and also rushing to get my little LAMMPS GUI toy into a usable state, so people - specifically those working predominantly in graphical environments - may consider it as an option for the tutorial sessions at the workshop.
I am happy to share my current draft LAMMPS-forum-readme.txt (3.3 KB) in case you’d be willing to help edit and expand it and integrate the suggestions, where meaningful. Please also note that we have a dedicated webpage on the LAMMPS homepage with more detailed guidelines (originally conceived for the mailing list), Guidelines for posting questions to the LAMMPS forum. This likely needs some more editing and updating and synchronizing with the pinned “please read this first” post. The website would allow to keep the pinned post concise and have all more detailed explanations on the homepage. That one is easy to update as well: guidelines.txt (7.2 KB)
