The former administrator of wakachan.org/azu has provided me the latest available archive of the site data for the old imageboard. The most recent post is dated 12 December 2015. It is available at https://ib.axypb.net/archive/azu/wakaba.html
and in the "Archive" link at the top navigation on each page. Feel free to repost images from the archive to this site. Be advised that this is a static backup only without the Wakaba scripts in place, and so post controls and reporting features are disabled.
Regarding the old content, I would like to propose the following. As I stated in the "Welcome Back" thread, the post data from the old Wakaba-based board is incompatible with the current software, but I have received an offer to have the data migrated. The former administrator has provided only the static threads and images. I have requested the database dump that corresponds with them, which is necessary for a migration of the old posts. Upon receipt of this data, I will forward it to a specialist who will then attempt to convert the post data. If successful, all archived posts will be moved into this site. The address of this imageboard will not change.
I have opened a Straw Poll to decide whether to move forward with the data migration. The options are to leave the archived posts in place in a separate area of the website or to attempt to integrate them into this board. Feel free to voice your concerns and reasons for your decision.http://strawpoll.me/6569858
