For the last year we have had 2 flavours of ManageFlitter: the free version of ManageFlitter and the Pro version.
Over the next couple of weeks we will be making some changes to the free version - the Pro version will stay exactly as is.
Don't worry - you will still be able to use the free version as usual but with a "bonus system" in place.
We will be rolling out a "bonus" system whereby you have the option of sharing the ManageFlitter love and increasing the number of people you can unfollow per day and/or gain access to some features.
Currently all free users have access to a limited feature set and can only unfollow up to 1000 people a day. With the bonus system free users will start off with a limited feature set...
