A suggestion: I think this either starts off Big picture, or little picture.

Either start off by creating a list of sites under threat then developing a set of activities that encorage local groups to form Action Groups, with RASCALS (Radical Action for Sustainability of anCient Areas and LandscapeS) acting to promote these groups and raise general awareness of all sites under threat - working towards a remit of intense co-ordinated lobbying and awareness activities.

Or

Pick on a single issue, such as Silbury Hill and be that "local" Action Group with a view to future expansion.

This second point is the direction FoT has taken, and I think it has a lot of merits. There is nothing to stop us forming alliances with other parties and we get genuine first hand knowledge of what goes into a campaign, including the non archaeological issues that serve to strengthen the overall campaign. This smaller focus means initial activites can be limited and therefore the groups resources are less likely to get overstretched too soon. Taking on all comers, whilst we would all like to do this, will only result in this group being toothless and inactive.

It should also be remebered that any campaign is best driven with a strong local element. Local people do not like outsiders coming in telling them what to do, many are more concerned about the possible impact of increased tourism than they are about the monuments themselves, so unless they are already organised care must be taken.

The concepts and aims are coming together nicely now. Bubbling up from the comments made is the issue of approach. What I mean is - will the group be about putting forward reasoned arguements, gaining effective publicity and being "respectable"? OR Will it be about taking confrontational action, protests , eco-warrior type stuff?

OR BOTH

Being "both" is what is really needed, but that is a large part of the problem we have of finding a suitable name which encapsulates our identity. So why not consider having TWO identities for one organisation and using whichever one is most appropriate?

For example: The Prehistoric Protection Society (PPS) sounds very sober and respectable. This could be our negotiating, persuading wing and would feature on notepaper etc

The Prehistoric Action Group (PAG) would be our banner waving, site squatting, slogan daubing action group.

Both names contain "Prehistoric" which has been a major concern of members and both would get picked up well on web searches. I would suggest seperate web sites too.

5. We should be Ireland as well as UK.

All for that , but! ...

You are then having to manage two legal systems and arguments used for the UK might not be valid in Ireland.
