You know you need new software when...
It doesn't say much for your software when an out-of-office message effectively broadcasts the problems you're having with the software.
...you start leaving out-of-office replies like this one that I saw today:
Wow. This guy has serious job security. It sounds like SharePoint problems are a matter of "when," not "if." Whatever the system, if you're creating out-of-office notes like this one, it's time to start searching for alternatives.
Anyone else seen similar out-of-office replies? Your answers can include problem open-source products, too. I want to see one that says something like, "[Insert product name] is about to self-destruct. While I'm away, first take a Valium. Then call my mobile."
Disclosure: I work for Alfresco, an open-source alternative to SharePoint.
