currently, when you assign points to a post, if you make a mistake you cant correct it(it says something like "you have already submitted anti-points for this post"). now, i know i have made mistakes a few times, and would like to be able to correct them. wouldnt it be pretty easy to make it so you could change your assignment...just a few lines of code like:
if(antipointsassigned < 0 && newassignment > 0)
assignpoints(newassignment);
else if(antipointsassigned > 0 && newassignment < 0)
assignpoints(newassignment);

obviously this is just a rough outline of what would be done, but you get the idea.
