well, today I enabled the user contact form and tested it. The form works but I received an error from PHP about a deprecated function. Here is the link to the fix:

To be honest, I’ve had more luck installing these patches manually than using the patch application from the command line. I might be doing something wrong but I don’t think so. I believe that what is happening is that the patch is issued for a version of the module, at a specific line number. Then, the module is changed and the line number changes but the patch isn’t necessarily committed to the module. So the line numbers no long match. Or, I am an idiot who doesn’t know what he is doing.
So i usually open the patch, check out what is being changed and add it manually with Aptana. that way i have to look at the code too.
