Can we delete our discussions that have not recieved any responses?

I'm also the same as you, I keep everything organized as much as possible. I clean my inboxes here, also try to keep my numbers "even" before I sign out. I don't think you can delete discussions with no responses, as I am also having troubles to keep my own discussions noticed by other members and resolve it. Just don't mind them that much, try to keep on posting more and concentrate on how you could share some knowledge here!;)

I think you cannot do this on mylot and for more information contact the administrative of this mylot or the site.

you can't by yourself, one of the defects of mylot is you cannot edit and delete your posts freely, so if you want to delete or edit your discussions you have to contact the admin and whic is not recommeded!
