Wiki configuration – it’s obviously a Wiki page itself – what
else! In summary, server-side it’s an Intranet running Windows
Server 2003 SP1, PmWiki 2.1.11 and Apache. Our Wiki is just over 1200
pages, of which an average change/edit rate is around 200 per month –
around 30 authors. We’ve run this configuration for a long time now
(over 12 months) and it works great :-)<o:p></o:p></span></font></p>
