Everything important. Sending messages, exchanging files, etc.
What does not
The default organization scheme does not allow you to select items in your account (files, mail, etc). However, you can change the scheme by clicking 'view' on the top bar of the window and selecting 'View as List' or 'View as Index Card'.
If you click the 'Setup' button at the login screen, the setup menu takes several minutes to load, but works fine once it does.
What was not tested
As a student, I have yet to have any problems running FirstClass on Linux.

If you install the Linux version on the same computer as you have the Windows version under Wine, both might share the firstclass folder in your home (~) directory, depending on Wine setup.
This means that saved login details and settings will be accessable from both the Windows and Linux version. As the Linux version is older (at the time of writing) than the Windows version, you should be aware that if FirstClass was to change settings formats this may cause problems. I have however not noticed any, my settings are loaded fine by both the Windows and Linux clients.
