and just what is 'orkut'??

if you mean an invite to gmail, invite yourself. pretty straightforward.

"Orkut is an online community that connects people through a network of trusted friends. We are committed to providing an online meeting place where people can socialize, make new acquaintances and find others who share their interests."

It's apparently a social networking community with rather stringent membership requirements. You must have, for example, six fingers on your left hand and no tattoos above the waist. The "Interests" directory includes: Locomotive collecting, Toilet Tissue Origami, Putting Things On Other Things, Hand-rolling cigarettes, Frog Strangling, Vowel-counting in the Classified Section, Misspelled Roadsign Census, Liferaft Watching, and similar.
