Voting starts in March for the Drupal Association Board election.
With the 6.x version of WYSIWYG module, when you activate it with tinyMCE (didn't test with others editor as tinyMCE is the only one "supported". But the split summary button (one of the new functionnality of D6) don't appear anymore...
With the editor enabled, I can understand to hide it because it's not very usable to let this button separate from the others of the editor, but, the break function should provide this possibility so (it's not the case atm).
But with editor disabled, the button is still not present, this is not a normal behavior IMHO
