I have a large file of normal (not replies, no links) tweets generated, and about 120 accounts. I want to connect with 4 accounts at a time and post a random tweet from the file about 4 to 5 times over a couple hours, then move onto the next four. How do I do this? I can only seem to be able to do all the accounts at once, post a random tweet here and there at random times, not stopping until I hit stop. Thanks.
