Google has introduced some great new features to Gmail and Google Talk

Google Talk

Orkut, as we know is an Internet social network service run by Google and named after its creator, Google employee Orkut Büyükkökten, has given us another great feature. You can now login to your Google Talk and get all your Orkut friends there in the messenger. So no more scrapbook hassels, if your friend is online, just go ahead and chat with him/her.Its interesting how you can scrap directly from Gtalk. Orkut friends will automatically appear in your Friends list, and you’ll find out instantly if you’ve received a new orkut scrap.

Offline Messages
Now if your friends have chat history enabled, you can send them messages even when they’re not online. Just enter a message into the chat window as you would normally, and they’ll get it the next time they sign into Google Talk. In Gmail, offline messages can be searched and organized — just like instant messages in their chat history.

Gmail

Reply on top
No more scrolling to the bottom of a long message to find the “Reply” link. Now there’s a Reply button right on top, along with a lot of other options under the little dropdown arrow.

Embarassment-reducing new message notifications
Ever replied to a message only to find out that someone sent a better, smarter reply right before you? Now, if someone sends a reply while you’re in the middle of reading a conversation (or replying to it), you’ll get a notification that a new message has arrived. Click “update conversation” to see what you’ve missed.

Forward all
When viewing a conversation, use the new “Forward all” link on the right if you want to forward the entire conversation instead of just one message.
