The submit button for adding a comment (or a "correct path") does not seem to do anything. Tested on two problems, in the first node and on a missing variation. Has worked on the 13th, at least, to narrow down the possible reasons.
In case this is not reproducible, my setup is
Java(TM) Plug-in 1.6.0_14-b08
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.14) Gecko/2009090216 Ubuntu/8.04 (hardy) Firefox/3.0.14
Cannot add comments
Re: Cannot add comments
Scratch that, it is working now. most likely my java was misbehaving.
