how to edit a post?
 

So after I've posted something, how do I edit it? If i want to make a change, in the past there used to be an edit option but I can no longer find it.

did it disappear or has it been moved and am I suffering from blindness (not unlikely).

The board is set up so you're able to edit your post within one hour after making it. During that period there should be an 'edit' button in the lower right corner of the post. The edit button goes away after one hour.

If you want to change the post after that time period, contact the moderators by reporting the post - click on the white triangle with a red border and an explanation point in it, at the upper right of the post.
