You can create groups, but the process is not as smooth and automated as it could be. It's also easy to edit, delete and find entries. Juno, like CompuServe, offers an option to save incoming addresses automatically. If you absolutely, positively must have your files get through consistently, the best bet is still an online service. Click a button when you're composing an e-mall message on AOL or CompuServe, select the file from the directory that pops up and you're home free.
Problem is, even that option is close to foolproof only if the recipient is on the same service.
If an attachment won't go through, ZIP it and try again. If it still doesn't go, you may have to resort to snail mail. Adding attachments to messages using Internet Explorer or Netscape Navigator is as trouble-free as it is with the online services. Click a button and select your file, and the recipient will be notified that there's a picture of your kids or a budget spreadsheet attached. It's also fairly easy using Eudora Light, although you have to go outside the message box and pull down a menu to access the attachment feature.
