I've never been able to get Twitter Tools to pull tweets from my account, though, it does post a tweet when I make a blog post. I've never been able to figure it out, but today I noticed in my error log that one of the issues might be a missing table:
wp_ak_twitter. I've installed several versions of Twitter Tools and I don't think this table was ever created. (Why? I have no idea.)
Anyway, I can certainly make a table, but I need to know what the fields should be. If someone would be so kind as to post how the table should be and/or something to that effect, I would be quite grateful.
