Dear Benjamin,

Thankyou for addressing this issue, all over the web there are sites 
that require people to "look at the picture" and as a blind person far 
from home (at uni) it can be difficult to create accounts/whatever the 
issue was. (sometimes they have it for resetting passwords etc)

You mensioned the "nospam" pluggin, it sounds excellent, the OLPC wiki 
has a system where it asks mathematical questions and if the answer is 
correct the wiki changed are accepted. I do not know if they are using 
the "nospam" pluggin or something else.

questions such as:
99 minus 7
1 add 20
2 + 4
and as a blind user it was simply delightful to work with.

Thanks again for addressing this issue
