I would like to be connected to a friend of mine on LinkedIn, but I am not able to do that because I do not find the possibility.
I can only write a message, but to do that would I have to upgrade my account?
How is it possible?
I think about limitations setting by that users, but I do not know any of those settings.

I do have messages with a free account, so no, you don't have to upgrade.
There are settings regarding how to manage "invitations" (sorry if it's not the word, i'm roughly translating from Spanish)
If it's a friend of yours, the best way to handle this would be to ask him (by regular email) to contact you (by linkedIn) provided that you have the setting "anyone on linkedIn"
