GMs - all of the rosters are up and open for business. Please consult the Yahoo! forums for the most up-to-date information.
We do have a waiver wire crunch issue. I've been experimenting with different settings, and even if I make the waiver period 1 day, Yahoo is wanting to make Tuesday count as that day 1. In other words, waiver claims would be processed on Wednesday. I can't really tell if this has changed in the way Yahoo processes it, since this is my 1st year doing it. But even with continuous waivers (process on Tuesday) as the setting, it's telling me a claim will process Weds (!).
As eja mentioned, this would only affect 3 NBA games and possibly not a single fantasy starter, so I think it will be ok, HOWEVER, I am willing to conduct 1 round of manual waivers if necessary (i.e. GMs would need to send me their claims directly and I'd 'process' them Monday night).
