I keep getting hits for people looking to see if Opera works with Gmail.

Yes, yes it does.

Version 8.0 (the current Beta/preview, as of this writing) works just fine, with fully functional Gmail. Plus all the other Opera goodness. (Not to be confused with Oprah, silly).

OR Gmail now offers an “html” version that will work with lotsa browsers, but you lose a couple functions, seemingly things like being able to select all messages in your folder with one click, and with the pop-up box that helps you fill in e-mail addresses that you’ve used before.
And today? Gmail is instituting their “infinity plus one” mail storage capacity. *winks*
