Large Attachments
You can safely send and receive attachments up to 10 Megs in size. You may have some success with files between 10 and 19
MB. WebMail cannot accommodate any file larger than 20 MB. If you need to send larger files, we suggest you use Netscape Messenger. When in WebMail, you will want to look at the Size column. Any message with a size over 20,000,000 will not open.

Tab Key
Unfortunately, the tab key is set by Netscape and Internet Explorer to navigate to the next window or button. Instead of using a tab, it is best to use the spacebar to enter the correct number of spaces.
Severity: Low
Chance of being fixed: Low

Enter key to login
Yes and no. Netscape and Internet Explorer handle the Enter key differently. In Internet Explorer you can hit enter. In Netscape, you have to click the Login button. We hope to eventually have the Enter key work for Netscape as well.

Card Signatures from Netscape Messenger
Card signatures are created when a person sends a message using Netscape Messenger.The card signature works only with the Netscape Messenger address book. So when you click the button to add the address to your address book, it saves to the Netscape Messenger address book. We would suggest you not use these buttons. They are not supported in Internet Explorer.

Windows XP and Webmail
When using Windows XP without service pack 1, (SP1) or higher, Internet Explorer may not be able to access webmail. To fix this install Netscape 4.7.6, 6, or 7, or upgrade Windows XP by using the "windows update" feature from within Windows.
