Vincent,
Sorry but I misunderstood.

Bigtime noob. I was confused by terminology. Don't ask me how I managed that.
I have used webmail, like gmail, yahoo mail and hotmail. I was thinking of something else that might have been unique to traditional webmail service in feature/function. In fact, I was thinking of it being more like Outlook that was accessable from the web browser.
As for "desktop mail", I have used outlook express many moons ago when I first set up our desktop in 2003 but not since.
So, what you were saying was, that I could use Thunderbird, which is a desktop mail client, as I would Windows Outlook but recommending to use a webmail service instead, such as gmail.
I had thought that Thunderbird was Firefox's version of hotmail.

I had not really ever fully known the difference between the two honostly.
I was thinking of using Firefox and gmail for day to day stuff but I'll have to determine if/why I'll even need Thunderbird then(desktop mail client), as I don't really know why I would use it as opposed to gmail.
Sorry for the confusion.
This should start a fire back at the shop.
If you could explain how/why you use one over the other, I'd like better understand this.
By the way, I appreciated your patient explaination to an otherwise noob misunderstanding.
That makes for a good teacher!
Thanks again,
