Connect, follow and endorse
XpertConnect
Press XpertConnect on someone's profile. They get a notification and can accept or decline. Once they accept, a Message button appears and you can chat.
To keep things friendly: up to thirty requests a day, and after a request is declined you can ask again only after thirty days.
Your lists
On your profile page, tap followers, following or connections to see the people. Each connection has a Message button.
Follow
Following is one-way and needs nobody's approval. Your profile shows your followers, who you follow and your connections.
Endorse
If you know someone is good at something, press Endorse next to that skill. You can endorse each skill once, and never your own. The person gets a notification.
Report
If a profile is fake, spam or abusive, press Report. A moderator will look at it.
