You're welcome.
Your followers can grow quite nicely with the right tools (I'm around 5000 after roughly a month and a half), not so long ago I would have told you to try the free version of TweetAttacks but you can't anymore as they've just closed down due to a complaint from Twitter...
I have another tool that's working just fine but not so long ago there were a few problems to download it, so I've just asked them if the problems are solved. I'm waiting for their answer, I should know within a day or so, when I get the confirmation I will update this article.
