[pmwiki-users] group naming

[Hans]

Hi,
for a web-based publication project I need to create a group for each
new week (issue) and I wish these names will list nicely in
chronological order.

If I choose names like RB 05 Week 13, RB 05 Week 14 etc
they display as R B05 Week 13, R B05 Week 14.
Is there a way that they display as inteneded, with  a gap between the
initial letter(s) and the number for the year?
Can group names start with  a number?
Any other clever ideas how to create readable and useful groupnames
for this?

Thanks for your help in advance!
