[Koha] How many libraries use Koha?

[Chris Brown]

Hello,

I have agreed to give a webinar on Koha to a group of community-managed
libraries here in the UK. It would be interesting to include some basic
facts and figures:

* How long has Koha been in existence?
* How many libraries around the world are using it?
* How many active developers are there?

Does anyone have estimates for any of these?

Thanks!

Chris Brown
