This has caught me out a few times, though I am now getting used to it. The forum uses two formats for dates, MMM 'YY for dates before Jan 1 (currently), and MMM DD for dates in this year. The problem is these look very similar, so similar I have a few times caught myself reading them wrong. One example is the first and last messages in this thread:
Or it's easy to see in the dates in this area of the forum, when topics are sorted in date order.
It might well be as I am British, so am not used to US date formats. But that probably applies to many forum users. An option to either use local date formats or to never abbreviate years would make dates much more readable.
