OpenMandriva is no longer using Freenode IRC. There are Matrix channels for OpenMandriva (user channel) and OpenMandriva Cooker (developer channel). These are also channels at Libera Chat. #openmandriva @ libera.chat and #openmandriva-cooker @ libera.chat. The Matrix and Libera Chat channels are bridged (interconnected). They are also bridged with Telegram.
