When failing to create a trigger due to a poor cron input I noticed a couple of minor GUI glitches
1) The help link is too near to the error message at least one space is needed
2) The error message is not highlighted in red and at the top of the screen in an alert
3) Help is a link to an external site outside the control of the organization that deploys the local instance of Sakai.
4) Help is a link rather than an icon.
