I realise it's somewhat early to suggest this, and that it probably will happen anyway, but will all the Errata corrections posted collected somewhere centrally soon?
Format the errata in a PDF with a filename that indicates the date (i.e.: T20Errata10242002.pdf). Within the files, organize the errata by Chapter headings, then by page number for easy reference and lookup. This would be very similar to how WotC posts their FAQ's on the products. The link to the file would be on the errata page, along with a small blurb about the latest errata file.
It's a great idea, you can tell at a glance if you have the latest version of errata by looking at the file name. You can then discard old versions if new versions come out.
Its also easy to mantain on QLI's end. They can mantain the errata in a word document for easy editing when more errata or clarifications are discovered/added, then convert it to PDF for posting to the website.
Actually, I'd have thought an HTML or text page would be a lot easier to maintain. Saves farting about with word documents and PDFs, and is much easier to update. Something like the SJG book errata pages would be more sensible, methinks.
For example:
I'll get an Errata/FAQ page up probably this weekend with the current information we have so far, and try to keep it updated weekly with the CotI updates.
It will be available as a PDF and Webpage for ease of use.
