In my site the profile has very sensitive information, so almost everyone will turn his profile into "only friends". But they want to make friends.

What am I going to do? Isn't there a way to manually do so? Which files have I to change?

Thank you.

It would take some special coding to do what you want i believe.  And would require a coder to do this as this would be a special project.   It sounds like you are using the preferences beyond there intended scope the way it is now.  But i do see your point and i do see that it could be an issue.  I do agree there needs to be a happy medium.

Basically they have locked each other out and if one does not give in then they are both blocked, its a preferences standoff.

The only thing i might suggest is that they make one day of the week, "new friend day"  and change their preferences for that one day to allow everyone.  Then they can go back.

That is all can think of at the moment.   If you want a special coder check out the "market" link in the menu above on this page.

So I have to find someone who is a coder...

How I can post to market? I signed up at "odesk" and I choose "post a job to odesk" but it sends me to make my profile as a coder! I cannot find where I have to go to post a job for someone else to do.

Just log into your account from that odesk page page and then you can post a job from the menu available.
