I've finish the upgrade of following part of my site:
  1. Forums at forums.waltercedric.com now use the latest Simple machine Forum 1.1.2
  2. Wiki at wiki.waltercedric.com now use PHP5 and WikiMedia 1.9.3. I only encounter the error: Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 46080 bytes)
    which can be solve by increasing the memory_limit variable in php.ini
  3. The demo site at demo.waltercedric.com and its admin section is up and running
Please report me ASAP any problem in the next few days if any.

On the Joomla side, a new version of securityimages 4.2 is currently in development, bugs correction, a check your install page,  a new captcha engine, named calculator (15 + 8=) is what this new release bring.
OpenComment will follow also soon in a version 3.0.30.
