its been going on for 18 months now since the initial announcement.
None of what is written (well most) is new and has all been regurgitated and discussed multiple times already in several main tax threads. Many of the original posters have simply switched off which is why you now have a particularly relatively new member posting information that he seems to believe is new - like the RD explanation booklet.....
The simplistic reason for a potential lack of accurate answers is that TIT and lack of clarity can allow all sorts of things to take place........Also what is accurate for one is not necessarily true for another hence the repeated suggestion to seek professional individual advice if you are that concerned.
