Does exactly what it says

I tried a few other tweet-old-posts plugins, but even ones recently updated refused to authorise twitter, this one authorised in an instant.

Great features, but there are a couple of things:
Hashtags from post tags doesn’t always work. Doesn’t seem to be length related, bo idea why, just a minor niggle.

Secondly, more of a feature request really,

If you are setting multiple tweets to be sent, a timer between the two would be nice, either that or change the number of tweets per hour, change that to tweet every X minutes (min of 10 minutes so you don’t spam everybody?)

All in all, a great plugin that’s gonna stay firmly activated on my site.
