probably have been threads about this before but this should be brought up again, but we need an "edit" button . when we create a thread , and we forget to add something , we should be able to edit that post , but it would show that it was edited in a different color . posts shouldnt be edited but i believe that OP should have the ability to edit that first post .
This is so because sometimes you make a thread and you click "create thread" and then you realized you forgot a big part of that thread . now , you have to make another post . the problem with that is that that post , wont be on the 2nd page , 3rd page , 4th page , etc. (you know how the original post is always on every page) . so , that important piece of information that you forgot to put in , may now be left unseen in the pages after .
