My new upgrade to version 2.3 looks to limit my address book to 5 PCs. Does this mean you plan to start charging for your product. I have 20 computers in the address book of my friends that I help. I can have research paper writing help for now. A limit of 5 will most likely mean that I will not be able to use RA. Why is this being done and will the amount be removed or is this a way to limit its usefulness?
