The problem The existing EA Forum codebase is relatively old and steeped in technical debt. New features and bug fixes (of which there are many) are slow, hosting is expensive, and server crashes are often time-consuming to fix. CEA also has considerably fewer resources dedicated to the forum than in the past (currently less than one full-time engineer), and we want to ensure the forum can continue to thrive in perpetuity whether or not that continues to be the case.
