It hurts to exclude people from the team, but...

We have some people on our team that were less appreciated by other members at first, mostly of their attitude and behavior. So I guess this is the same scenario.

I think the best thing to do is to be patient and to show them that you appreciate what they do good. Try to get the other members to do the same.

This worked in our case, most of the "problem cases" turned out to be great guys/gals and are really helpful.

So yes, patience is the the way to go.
