Kinda confused by what you are saying.
If he posts a link in his siggy saying that players can find good useful information here (insert link), I do not see how that would violate any of Outspark's rules, and it also does not say that every player has to follow it.
I think sylfin found the info. useful and would like for everyone to read it, but we know that it is not required. Posting a link is also not advertising, I was just saying that word of mouth is the best advertisement, not meaning to go out an place an ad for it. I was using it as a reference, towards advertisement, means to spread the word about a certain thing, and the best way for sylfin to do that is by word of mouth.
Like I said, I am confused by what you are trying to say, so maybe I am misinterpreting your post.
