git:master: modules_k/cfgutils: Added note about the core_hash function not being secure to the README

Update of wiki write access

by Daniel-Constantin Mierla

Hello, just to let you know that over the weekend the ACL (user authentication) for write access to wiki portals of the project has been turned on. Anyone that wants to write to the wiki has to create herself/himself an account. The reason for requiring user authentication is weakness of the captha system used for anonymous posting -- during the past weeks lot of wiki pages were updated by spam bots. If anyone is aware of a stronger captcha-like system to be used for anonymous posting, write back here. It has to work with dokuwiki. Cheers, Daniel -- Daniel-Constantin Mierla Kamailio Advanced Training, April 23-26, 2012, Berlin, Germany http://www.asipto.com/index.php/kamailio-advanced-training/
