You can download the zip file of Wieldy. Just unzip the application, as there is no installation of Wieldy itself required. But the target system muss be running windows and also the .NET Framework 3.5 SP1 must be installed prior using Wieldy. Unfortunately the installation requires admin rights. If the .NET Framework is installed on your schools system, then you can use Wieldy. Else you may need to ask the admins to install the Framework.

Will be implemented soon

Fixed with beta V0.2.6.681.

Starting with V0.2.7 the setup will contain an option for this.

The errors will be fixed with the release of V0.2.7

I already recognized this issue. I will fix it soon.

Fixed with beta V0.2.6.678

What do you mean with "make it an outlook plugin"? Do you mean to integrate Wieldy into your Outlook? If so, why would it need to handle E-Mails then?

Actually Wieldy can Synchronize your Contacts and Calendar between Outlook and Wieldy. It could also synchronize your Todos, but i disabled this feature in the current releases. If i would also Sync E-Mails, Wieldy could theoretically replace Outlook.
