I don't know what's up with the 9:30 club emails. I got them for years, and for the last 6 - 9 months, it's very spotty (more misses than arrivals). I've re-signed up several times, and with two different email accounts to ensure it's not just a spam problem.
I missed the email on the Liz Phair presale, but luckily (or not if you're worried a presale will sell out lickety split), I googled "Liz Phair presale" and was led to a blog that had the password and link. So thanks blogger for posting that info for the whole world. [Argument over posting of presale passwords may now commence.]
I got my four tickets and can rest easy, waiting until the next presale notification I miss!
