Hi - after some hard searching I found out what to do:
1. get a yahoo account
2. sign in
3. go to https://siteexplorer.search.yahoo.com/mysites
Step 3 I found here - http://www.designwebgraphic.com/web-design-blog/using_sitemaps_for_big_t... - thanks
Try finding this on Yahoo or via Google - it is just a joke and especially in Yahoo they are sending you around the bend with lots of grand words "We have listened to our users and ..." - nada, zilsch, 0 - not a link to got me there easily.
Well - I hope this will shorten the search for someone else - good luck
