Long time lurker, only now finding time to start posting.
I've noticed that the official ArM5 errata on the Atlas games site now includes a section labeled "New Errata." This, IMO, is a great step in the right direction, as it helps me to more quickly identify what's changed since I last downloaded the file. I've also found that it's much smaller than it used to be by omitting simple typos from the list, another good step.
I've got one more suggestion for Atlas. When this errata page is updated, could the date of the update be posted somewhere on the page? A natural suggestion would be on the same line as, or soon after, the "New Errata" heading. This would help those of us who try to keep our errata pages regularly updated to identify when a change has actually occurred.
