If you open one of your hotlists, I can't see how to move them. However, if you open the list of hotlists (if that makes sense - kind of top-level) - click search-my hotlists but don't click one of the actual hotlists in the flyout menu. Next wait ages for AW to produce the f-ing list, then expand one or more lists using the + on the left. Each entry will have a tick box between 'notes' and the profile name. Once you've selected the one(s) you want to move, scroll right to the bottom of the page, and drop down the 'select action' box, choose the 'move selected to' option, and click save. Wait another eon and job done.
I took some screenshots to be extra helpful, but I couldn't work out how to insert images on here - when I click the Insert Image button, all I get is the start and end placeholders (I think that's roughly the term)
So, over to someone else to help me with that one!
