[GRASS-user] Cannot get past Wiki captcha

[Markus Neteler]

Hi all,

FYI:
I have modified the captcha in the Wiki today and
added a modification to mix image and ASCII for
the simple math exercise to solve when
- registering a new user
- adding a new page
- adding an external link

This should help to keep even the improved spambots
out (at least for a while).

In case of troubles please notify me. I am running this
already on the OSGeo Wiki for some days, looks
pretty good.

Best
Markus
