It is good if the current devtome situation has been fixed, but the issue of being able to sign up new recipients - can or has this been addressed?
As the primary devtome situation seems resolved it's being looked into.
A reminder - could all existing users that've been unable to edit/add check it's now working (even if that just involves a quick edit - save - undo -save). Then we can file that aspect as universally fixed.
How about a global notice in the header stating: "We managed to fix the issue with creating/editing wiki pages, if you happen to have any issue please report HERE (link to this or another forum thread)"
