We recently added OAuth to MentionNotifier so that users can quickly view and edit their subscriptions without needed an additional login.  This is enabled by default for new users, but existing users will need to do the following steps to associate their subscriptions with OAuth:

1)  Go to http://software.engraph.com/ManageMentionNotifier

2)  Click “Sign in with Twitter”

3)  Verify that your twittername and email are correct

4)  Click "Associate with OAuth"

This will also allow you to reply to notification emails and MentionNotifier will tweet on your behalf.  This is made possible by @sidePop written by @ferventcoder

Note that the reply by email is new and buggy, so make sure that what was tweeted is correct and as expected.

If you run into any issues, sent me a reply to @timhibbard.

You can also join the MentionNotifier fan page on facebook, or follow @MentionNotifier on twitter.
