'first_paragraph' on f/admin is not useful

This isn't really the main administrative page.
The column headers describe the page content. If anything, the menu
title itself could be changed to 'Newest users & groups'
'Articles' should change globally

'Articles' is innapropriate, but there are a few options for this bit:
'Items ordered', '# items ordered', '# items', 'Item count',
'Order count'. I'm not sure that any one is clearly best.
Removed 'bearbeiten', added 'search'

Im not totally clear on the meaning of bearbeiten in this context
but it seems redundant with 'edit'. The url token makes it impossible
to make this what I would prefer:
'Here you can search, edit, create, and delete users.'
Improved grammer, used same terms as for users

Again, the token makes it not possible to read as:
'Here you can search, edit, create, and delete workgroups.'
Improves copy
Improves workgroups:second_paragraph copy

Makes paralell with ordergroups copy, corrects a/an articles, makes
emphasis more specific.
Makes emphasis more specific

Makes placement of italic text parallel with workgroup:second_paragraph
