Personally I'd replace google alerts with https://mention.net Much more powerful IMHO. Disclaimer: I work for mention...
I installed it but couldn't log in with my Google account. I clicked "Sign up with your Google account", completed the Google accounts popup, and then the Google accounts popup was happy and it went away, but then nothing happened in the Mention window..
thanks!
spelling mistake on the windows GUI: "Personnal Settings", bottom of 'edit alert'
