I appreciate the responses and the explanations. This information should have been made abundantly clear on the wiki. Perhaps a huge banner on the main page (before the change) that a change was about to occur, why, where to find the discussion, etc.
If it wasn't obvious by my confusion displayed here (and the confusion I'm hearing from other community members), the lead should have been taken anyway to ensure this change and the reasons for it were clear and obvious to anyone visiting the wiki on a regular basis.
Some may wholeheartedly disagree that this is a valid discussion forum for the wiki, so I do suggest a proper discussion place be assigned and (again) advertised to anyone who visits the wiki on a regular basis.
I also would at this early stage (for me) suggest that the Legacy pages link from the main page be made bold, red, flashing, whatever, so that those who are not used to simply using the Search field have some signpost indicating where the old content lies. (indicating clearly that the old content still exists)
All that said, I do worry about this change. It may have been necessary for legal or logistical reasons, but there has been a consistent cry that the old content was disorganized; far too disorganized to be fixed, that it must instead be completely reset. I strongly feel that the saying it was beyond repair is overstating it quite a bit and that resetting is a task that will likely go undone. (especially if we do not make strong efforts to keep the wiki community we have well informed and supported)
I hope that this discussion does not cast a bad light on me, as my tone and efforts have been simply to disclose this information and the plan going forward for all wiki users to see.
Thank you for your input in this discussion. Here's to seeing the wiki reborn.
