If I made a typo in my question and I am afraid that you would misunderstand the entire question, is there any way I can edit it?
you can't edit it after you send it, but if you send it again and let me know it is an edit, i am usually very understanding about it. i will post the one you meant, and not the one you didn't mean, and even switch it if it's already posted. and also edit out the editing instructions
