is it necessary to be 18 and above to join orkut?

Idont think that they have any bar on the age of the account holders, but even if they do so, it would be in the health of the users. Orkut does contain some adult stuff and besides one needs to be very careful while posting messages on these public sites.

no need of it many of them are below that age

i dnt think so, anybody can join the orkut. In order to avoid malpractices of orkut users, age can be fixed to 18 years.

It is neccessary that you should be 18 while you join Orkut because orkut has some mature content which is not allowed to the minors and there are also the discussions sometimes which can lead to the wrong path for minors. Yes I know these days ,minors are also quite smart but it a rule and it should be followed.

i think der is no such rule in orkut anyone can join orkut irrespective of their age limit

Yes it is!!!!

i think it is not necessary to be 18 i have joined it when i was of 17+

i dont think so i have joined iorkut when i was of 17+ and i think there is no retriction of age there in orkut

i think orkut contains some mature content so its important that ur matured enoughto handle the issue with some sense and also dont misuse orkut
