So I emailed Alex (like the directions guide me to) in order to get an
account on the Trac to submit a ticket in which to add a patch to
Instiki to add captcha functionality. (Wow, was that ever long to
write!) I recently received an email saying that his mailbox was full
and that he did not receive the email.
Is anybody here friends with Alex or knowledgeable of what’s going on
with Instiki and Alex? Is there another avenue I can go? Has Instiki
been abandoned?
Just curious: I think this Patch might make it in!
