[glend (Glen)]

Maybe it would help to call it as a Star Party type event with a name like Lake Chaffey Astro Camp, or New England Area AStro Camp/star party, etc as "Very Early Notification" title doesn't tell people anything and can be missed by people browsing the New Posts in the forum unless they make the connection to the sub-forum it's listed in.
I've tried to search for users by area/region and that doesn't seem to be possible for a normal user. If you were really good with SQL you might be able to write a script to pull out user location data but that's maybe going too far. Best bet might be good publicity.

I will PM glenc and see if he knows of others in the northern NSW region.

Update: I have had a message back from glenc and he is going to let others in his area know about this event. Arthur can I suggest you edit your original post title and give the event the name of your choice. Cheers
