Due to a technical problem, mail service for mirbsd.org is not available. tg@ is also absent but you can reach a MirOS developer at bsiegert at gmail.com (replace " at " by @).
Most notably, this means that the mailing lists, miros-discuss and miros-cvs, are not working. To keep up with recent commits, look at the Changelog. anoncvs and cvsweb do work.
