[pmwiki-users] Recent Changes customisation

[Simon]

2 questions
Q1
I have in config.sys
  $RecentChangesFmt['Main.LastChanged'] = '* [-[[$Group.$Name]]-]  ';

I want to suppress the group name and have tried
  $RecentChangesFmt['Main.LastChanged'] = '* [-[[$Group/$Name]]-]  ';
and
  $RecentChangesFmt['Main.LastChanged'] = '* [-[[($Group.)$Name]]-]  ';

Neither seemed to have an effect.

Q2
can I simplay change the default so that the RecentChanges page of every 
group is in fact an AllRecentChages page?
