I think the important point to stress is that this is not an attempt to compete with any existing societies, rather it is a step to enable AditNow forum users to join in with trips to places which require insurance.
For example, several of the AN forum users going to Snailbeach on Sunday will be covered under the ANHMS insurance. Without this, the trip would be a lot more difficult to arrange and co-ordinate. The great benefit that the Society will bring is that it will greatly aid AditNow's ability to organise trips to places that require insurance - for example Milwr, Parys, Snailbeach etc..
Primarily, AN will easily be able to provide the insurance numbers for members attending without any of the hassle of chasing attendees up and/or running the risk of people being found not to have insurance at the last moment (yes this has happened, albeit not with AN!). Whilst this certainly does not exclude those who already have insurance elsewhere, it should open up trips to more people by making it easier for them to gain the requisite insurance.
It was also felt that AN could have encountered problems with arranging trips to some sites simply because it wasn't a society or club. Again, the aim is to enable more trips to be organised and for more people to participate.
Thus, this move should hopefully enable people who have not
participated in trips to do so. And indeed, as Simonrl notes, there are links to other clubs and societies on the sign-up page, so AditNow will continue to promote the work of others.
I'd also add that AditNow has been actively involved in a number of preservation/restoration activities, in particular at Cwmorthin. Hopefully these sorts of activities will continue well into the future and the ANMHM will make a useful contribution in its own right.
