Blogger to Twitter autopost issue

Hey everyone,

Years ago, I registered to a website and set up a system so that it would check my blog every 3 hours and post the most recent blog to my twitter account. Since this was years ago, I have no idea on what site this was and I want to desactivate it now, how could I proceed? I mean, there must be an easier way than to check my old emails and try to figure out what website it was?

Thanks for your help!

Check the applications that use your Twitter account, find the one that's you need and deactivate it.

This is in Settings > Apps.
