After my posting last night, I went back to Yahoo's fantasy sport home page and went through the motions of "joining" a group using the group ID and password that was set up a couple of months ago (by iambrutus I believe). It took me to what I usually see but only 2 members were in the group (myself and LongBallin Buckeye). All of our messages were still there, going back to January 5 and when I selected my team for this weekend it showed my team total score of 1013 on my selection page, yet on the group's main page it showed my team score as 0 (as well as LongBallin Buckeye). It seemed that it had a 'memory' of what I had done so far (for example, who I have activated and how many times).
If our prior existence is gone, I agree with Wingate that we start a new league for next week's tournament.
