It wasn't recognizing my username and password so I tried to reset the password but it asked me for my phone number. I only used my phone to tweet via text messages once or twice, a long time ago. So I filled in my phone number but again, twitter says it's not the right one. Argh! I live outside the US so there's probably some code I need to put before my phone number, but I don't remember what it is. This never happened before! And now I'm locked out from trying too many times.
