What a shame. In the past I've enjoyed browsing through some entries and even contributing myself with a few entries. Without that "anyone can add an entry and without logins" part of it, it probably is going to die off.
Been trying to sign up as well but also not getting the confirmation email in my inbox or spam folder. Once I do get that sorted, I'm probably going to back up some of the entries I wrote so they're not lost forever (Or indeed, become harder to access.
)
