On the home page of this blog, I have a line with a typo: it says “We have me the enemy and he is us” and I need to change the “me” to “met.” But I’ll be darned if I can find where in the dashboard to change it.
Since your username is not linked to the blog in question, in the future could you please provide a link in your forum post to the blog you are talking about. We volunteers do not have access to the backend so we cannot see what blog you selected when you made the post.
Taking a guess, I would think you are talking about the tagline, which you can change at settings > general in your dashboard. Make sure and save after making the change.
