Everyone keeps saying that posting for domains will result in spam.
I'm pretty sure we would notice if someone posted 400 spam posts! Thats just a bit more than obvious.
And as for the store, there wasn't anything in there that can't be requested on the forums. There is a forum for the heliohost post for host account, and the only other stuff was name colors and stuff like that (and they were all sold out). So the store was pointless, but It was just kind of nice to see how many helions everyone had. I'm fine with it either way.
As for these other ideas, I think making people pay for coding examples (or hugs, or art, or anything else like that) WILL result in spam. People have to post to get helions, and they need helions to buy the code or hugs or whatever. So I think that is just an all around bad idea.
