[pmwiki-users] RFC: PITS 00701 -- WikiFarm confusion

I agree. My biggest problem with the Farm was conceptual. My existing
wiki suddenly became a field inside the PmWiki base install. It seems to
me that much of this confussion goes away if PmWiki uses the farm
concepts by default. Then there's no terminology required. We just have
many wiki's using the same PmWiki code base.

We'd need to change the installation procedure, to include definition of
the location of the first wiki, but I don't think it even becomes more
confusing for first time installers.
