The path is a is a per-account setting, so it's in the mail account properties page. You can get there by right-clicking on the name of the account in the folder tree, or through the menu ("Edit", "Mail and Newsgroups Account Settings"). Once there select the "Server Settings" for the account and near the bottom you'll find a "Local Directory" box and a "Browse" button (note that it's not an editable textbox).
I guess I have to set up an account to see this. And I have to do it in Windows first so I can see the shared folder I'd browse to. When I have time...
Lets face it Granny, you are a pretty advanced user. People new to Linux usually prefer not to go to the terminal and set up a symlink...
Who goes to the terminal? Not I! I use Midnight Commander to create symlinks. Have the source and destination directories in the respective panels, highlight the directory or file you're linking to, hit Control x, s and confirm the symlink's path and name in the dialog box, hit Enter, you're done. Harder to describe than do. If Control x, s is too much to remember, select File menu, symlink instead.
Midnight Commander is a treasure. We should make new users pass a Midnight Commander basics test before we let them use VL.
I don't use many plugins in SeaMonkey or Firefox, either. In fact, I haven't personally added any to either program. Opera has the main stuff built in. As for interfaces, I've always been able to customize Opera to my liking, and without going to some abstruse thing like About:Config. I'm writing this in SeaMonkey just for the fun of using something different.
When I use Firefox or SeaMonkey, I'm always missing my Opera features. I think my favorite is the whole-page (text and graphics) zoom in and out. FF and SM zoom just the text and Opera can do it with a single keystroke in 10% increments (0 zooms in, 9 zooms out, 6 zooms to 100%). I miss one-key keyboard navigation (x goes back, y goes forward). I miss having the option to automatically load at startup whatever tabs were open when I last shut Opera down--no need to make a bookmark set. I miss FastForward and FastRewind. I miss Speed Dial. When it came out I thought "ho-hum," but as I used it I found it really beats a bookmark you use frequently. I miss the Widgets, which can be very handy. I have a currency converter, a units converter (like Celsius to Fahrenheit), a link to Reference.com for dictionaries, encyclopedia, thesaurus, a weather widget. There are hundreds to choose from and they are easily managed, added, deleted, and they run only when you want them to. I LOVE fit to width, which eliminates that horrible horizontal scrolling you encounter on some Web pages and forums. I like having the mail program accessible as a tab in the browser. Don't get me started--I could go on and on.
The one thing Opera for Linux is lacking in is support for mplayer plugins. So if you need to run some Windows media file on the Web, you'll probably need to use Firefox or SeaMonkey instead. Every now and then I go to the Opera user forums to see if they've improved support for Windows media and I try whatever is suggested, but so far, nothing has been very good. No matter--it's no problem to start FF or SM and I often have them already running anyway.
