can i alter or update my discussion which had published?

Actually the only way is to send an email to support and ask them to delete your post (if there are no answers as yet). if there are - than you might ask them to correct it, but I am not sure they will do it. They did delete once for me a wrongly submitted photo in one of the discussions. Try writing them and let us know what they reply to you. Thanks

I don't think we can. I've been trying to find ways to edit my previous posts but never find a single tool here. I wish they'll allow us to edit our posts once submitted. It would be great if they do. =)

Unfortunately once a discussion and/or image has been posted on MyLot, same goes for comments and responses I should mention, there is nothing any member, including the poster, can do to change things.

You can post another comment under your discussion, but once you hit enter you are committed to what you posted.
