I have seen newbies ignored at the field.  I have seen members shun some newbies.  This only happens when the newby shows "attitude."   No-one wants to take a person with a problem under their wing.. Almost always the new guy or gal is welcomed and treated with respect.. When they show respect in return they have a successful learning experience.. When they tick folks off..... that's another story.  Do unto others as they do unto you..
