The "old" SharePoint Server 2003 offered the ability to display all alerts from a user on his/her MySite. MOSS lacks this functionality. So I wrote a Webpart, which will display all my alerts. Of course is multilingual. Currently there is English and German language support included. And it will work on Windows SharePoint Services V3. You don't need the Office Server for it :-)
You can configure which columns shall be displayed, and 
if you want to see all alerts from all websites within your SharePoint farm.
The Webpart will iterate through all websites, and look if there are alerts for the current user. You can then modify the alerts, or navigate to the corresponding website and list by clicking on the appropriate entry in the context menu of the alert.
To install this Webpart, install and deploy the solution via stsadm:
- stsadm -o addsolution -filename RH.MyAlerts.wsp
- stsadm -o deploysolution -name RH.MyAlerts.wsp -immediate -url http://yoururl
Instead of deploying the solution using stsadm, you can deploy it in the central administration of your farm.
Creating the solution wsp file is very easy, if you use the WSPBuilder.
Download the solution.
Download the source code for the Webpart.
(Please set the trust level of your web.config to 'Full'!)

Another small update. Handling search alerts is improved and the assembly will not install in the GAC (Global Assembly Cache) to get rid of the FullTrust setting in the web.config.
Update 11.06.08
This update deals with the problem that SPContext.Current.Web.CurrentUser is sometimes null.
