When I go to google+ page, I always see these messages: When their "capacity" not exceeded anymore???
I think that right now is only a beta version and they are testing it. I'm sire that very soon will be available for everyone.
if you want to sign up on google+ so you have to be invited by any existing member of google+ this is the method of sign up on G+
At this time you can signup with google+ only by invitation. You should ask someone who has google+ account to send you an invite.
When I log into Google + it says the following: "Send invitations - 150 left." I guess if you want an invite PM me your email address. Make sure you specify it's for Google+ and I'll send you one.
you can enter on G+1 button on any website and you have to login your G a/c your profile will create automatically.
it is not an easy task for google like always plays tricks ... you need to get an invitation to get into the google+ for its security... if somebody need any invitations just ping me up i will send a few ... hope i get paid for it as well
if the invitation for their social network is still on i would like to try it out. I just never figure out why they have a closed invitation if they want users to report any bugs found.
i just join, and have not added some friends there !it is a bit difficult though i think it will be helpful later !
