Pondering Upgrade Hell

i want to give a huge thanks, NOT, to all the bastards who dilligently slave to discover an endless series of exploits for every common web application...it warms me to know that "Hackers" are slaving away at this so scumbag spammers can make use of them...because of their laboring we are faced with the monumental task of upgrading the majority of our php apps...under any circumstance, this is a daunting job, as we have literally dozens of installs of several of them...unfortunately, every single install is customized with Corrinne's hacks, and mods, which are unique to each install, and tied into the core scripting...this means we have weeks of work to upgrade, and then integrate all those hacks into the new version...SIGH.
