the last few days I haven't been receiving updates / alerts via email and I haven't been getting all the alerts on threads I have contributed to either, but I don't know if that is a time related issue. At least I thought that might be a reason as they were 'older' threads but I don't think that applied before. It isn't the usual situation of one alert then any subsequent posts are just there. And I do have 'alert by email' ticked as a default setting. Anyway I just thought you should know.
