The MCNP Forum is moving to a new venue.
For as long as many MCNP practitioners have interacted with the MCNP Forum, that interaction has taken place via email. For much of its recent history, the email correspondence has been ephemeral, with no mechanism to capture it or otherwise preserve and make available the information exchange and knowledge gained. The MCNP team is changing that. We are pleased to announce the availability of a new MCNP Forum that is enabled by the Discourse software. The new forum is available here: mcnp.discourse.group. Please see the Forum page for instructions on how to join.
The MCNP team will keep the email forum operating for "a while" as folks transition to the new forum. However, we do plan to disable it, so to keep participating in the MCNP Forum, everyone
We hope that this provides a valuable knowledge capture and transfer mechanism with an improved user interface and experience.

A total overhaul is performed on the MCNP Reference Collection. The new webpage has a filterable set of categories that are assigned to each document to assist in navigation (with an “All” category that is similar in length to the old webpage). In addition, BibTeX-style citation details are now available for each document. Each document is also renamed to provide additional information in the filename itself.
Because of some of these changes, most old links to specific sections of (and documents within) the reference collection no longer work. All links throughout the MCNP website have been updated accordingly, but please be sure bookmarks are up to date.
