Like we can be digg friends and we can post here the stories we want to get digg and if you guys like the story you can digg it??? Or is this agains dp TOS? Just asking...
Personally I think it's a bad idea, but if you *must*, you can only post it in Buy/Sell/Trade -> Services since you are asking for the services of someone.
There was a "I'll digg you, you'll digg me" thread (or something a long those lines) a while ago and everyone on it got banned by digg. So i don't think its a good idea. You can however add people from here as your friends on digg, that would get more peoples attention to your stories, but not necessarily make them digg it.
I am in some digg club. However, it is not "i digg you you digg me" The first rule of the club is "Read the story and digg only if you like it"
I don't see why something like that wouldn't work... Just as long as it isn't implied that you are supposed to digg the story, that kinda defeats the purpose of digg. Just a place where you can view other members submitted stories and read them.
