Indeed. It was never setting itself up to be a truly great wiki, unfortunately.
We don't link there because of two main reasons. First, it tends to contain pages with false info and poor grammar. Second, we still see it as something that would draw away some of our members. You practically said it yourself. Another two reasons (albeit lesser) are that we have had bad experiences with it in the past, and also because a link to Bioniclepedia is entirely unneeded. I mean, where would we put it? We wouldn't make a page for it, because we just don't need one.
We're doing an "upgrade" at the moment, where we are raising the standard of all pages on Bioniclepedia, group by group. And as of now, there's hardly any false info anymore. All of the old false info has been fixed and the new stuff is taken care of right away. I'm not saying it's perfect, but it's in a much better state than it was say, about a year ago, when I joined.
I understand that you would think it would draw away members, but what I meant by that comment was that getting linked to by such a popular wiki would get us viewed a lot more, and the more people who stumble upon the wiki, the better chances we have of getting new members. Swert did say here that he was considering linking to us, so I'm guessing he was willing to overlook all that, but it's probably too late for that now.
I see. Well that's certainly good. But still, Bioniclepedia is not nearly as developed as BS01.
Still, where would the link go? We don't have pages for any wikis except BS01, and there is really no other place where it would be relevant or worth a mention.
