Hi Ambassador,
there have always been periods, when Oli had no time for vdiplomacy and actions like managing the variant development was neglected for some time. However, that was always temporary and I'm sure Oli will be able to continue his works here at some point.
You've really got bad luck, that you started your new variant when Oli's ability to manage the variant development was affected by real life business.
Of course, it could happen at some point, that Oli won't be interested to run this site any more, but I'm pretty sure he would inform us about this and won't just let this community disappear.
You're right that "at least one of the mods appears to have fallen off the radar". In fact we have two long-standing members of the mod team, who retired during the last months: Guaroz and kaner.
However, we currently have a mod team of five active members and are able to run this site without Oli's permanent presence. So I can assure, that this website will keep running for the next time and nobody have to worry, that vdip could suddenly just disappear. Just the variant development, that have to be managed by the Oli since that's the place where malicious software could be installed very easily, has stopped until Oli will have some time again.
