Bah. Gmail doesn't seem to be compatible with Opera. No fair.
It's nice, though, for what I can see. *pokes at it* Might start using it as my primary webmail account, redirecting my non-webmail account to it when I'm away from my own computer (on holiday or what have you)... my hotmail accounts are half-choked by spam and always on the verge of overflowing. I tend to be a packrat with email, I still have messages from years ago because "you never know when they might turn out to be useful", so I'm always just barely under the 2mb limit plain Hotmail has. So Gmail might suit me just fine.
Now if they made it work with Opera... I'm grumpy at the idea of always having to open IE to use it, I barely ever use that browser. Ah well.
(If you're wondering how I got a Gmail invite - Blogger. I'm no longer an "active user" of Blogger, having migrated to Movable Type, but my mother is - and she logged in today to find the invite, decided she didn't need it, and let me use it instead.
Of course, if you're really, really anxious to use Gmail, and you're worrying your username will be taken by when it gets out of beta, you could always buy an invite off Ebay. That'd put you in the "sad geek" category though - come on, paying for an early look at something that will be free anyway? Just to make sure you get your unique email address before somebody else can nab the username?)
