First, let me say how impressed I am with vtiger. It's both easy
to use and just makes sense as you move through the system, 
unlike some of your competitors.

I've run into a couple of very small issues in 5.0.4 that I have
fixed and tested. I also verified that the same changes need to
be applied to 5.1 svn.

The most important change fixes the Settings | Notificatiion
Scheduler so you can enable/disable the 5th, 6th, and 7th items.
The other change simply fixes a small logic oversight in the
module/Users/EditView.php.

Additionally, I added a check to see if the port was blank or not
in config.template.php.

How/where would you like these changes sent? Patch? Full
source code with changes noted? If as a patch, do you want 
the patches applied to the source of 5.0.4 and/or 5.1 svn?

Again, thanks for the excellent work!
