Certainly.
When I still had lurking privileges at WW, they posted a letter from PLN to WW. Apparently the mods at PLN were pissed that WW was bashing on them. From what I gathered, WW didn't like PLN because everyone at PLN just wanted to talk about dating and were only interested in finding mates. It was also a bit too restrictive, I think. (I can't even imagine.)
So PLN basically wrote to the WW mods and said, "Tell your kids to be nice to our kids or else we're telling!! And we won't talk to you anymore 'cause you guys are big poop heads." Or something to that effect. (It was very lengthy and included a lot of scripture quotes... gag). Their feelings were hurt and therefore they weren't going to let WW members onto PLN anymore. A couple WW members (and mods) were banned from PLN because they were big meanies and hurt PLN's feelings.
So then people at WW got upset and started throwing sand... wait, no, that was recess at the elementary school. No, WW people said, "We were never mean! Stupid PLN people!" and pouted. They were then reminded to be nice because we are all brothers and sisters.
That was all I heard about it. Sounded to me like a bunch of 6-year-olds, so I didn't read some of the posts on it.
Hope that helps!
