We think "connecting" or "friend requests" are largely irrelevant. This mechanism of connecting actually promotes some bad behaviors, so we avoided it all together. Either you're a member of the network or you are not, it's that simple.
The best way to "connect" with someone is to engage them. If they post a question, answer it if you can. Go to a Talloo event in your area and meet people face-to-face. Spend some time with them and continue to build the relationship in the app.
