[Mediawiki-l] Space estimation

[Sebastian Wallroth]

Hi there,

I'm asking for a friend who's English is even more worse than mine.

Is there any knowledge about the disk space a Mediawiki installation
needs? More special:

1. Is every revision saved? Meaning: if I change a slash into a
backslash in a text of 12 kB is the space needed changing to 24 KB?
And if I change a "then" to a "than" ist it changing to 36 kB than?

2. If I delete an article as an administrator, is it really wiped off the disk?

Thanks in advance,
Sebastian
