Just wanted to post a HUGE thank you to mbuser as well as an answer to my own question. I went into Yahoo's help, asked a non-related question and hit No that the answer didn't help to get to customer care (might be an easier way to get there but that's how I know how to get to it) and after I sent a few emails back and forth I now have my leagues I actually care about all under the right login (meaning I don't have to log in and out just to see the standings for my private leagues).
I just went to Help on the web page, asked some generic question in their automated help and then answered No that the answer didn't help me. That got me to the Customer Care section where I explained in detail what my situation was as well as league id's, team id's, user id's, etc.
They won't let you go over the max of 4 teams per id but they'll let you swap two teams between the id's.
