Over the years, we've found it generally more helpful to forgo these all-encompassing scope/rules discussions in favor of talking about very specific problems when they come up in actual practice.
This site is about Esperanto. I would begin your days embracing a broad range of interests so we don't start off by flogging newcomers with a patchwork of what on and off topic on this site.
In other words… let's not be too quick to jump on hypothetical problems until they become somewhat unworkable in actual practice. We have found that avoiding these forced rules discussions has worked exceedingly well for our newer sites; it makes for a much friendlier community overall. We may eventually need to enumerate some bullet points regarding what's on topic for the "help center", but it is way too early for that.
If you have a specific concern about something you're seeing on the site, please feel free to post a separate discussion about it here (on meta); but for now, I am going to close this thread as 'too broad'.
I think we shouldn't be that strict about what's on-topic and what's not during the private beta. It could be better to vote to close if one thinks that some question is off-topic for now. Then, when the site is more established (perhaps, after a week of public beta), some rules may be added.–None–2016-08-24T11:45:48.890
1The question is not about the private beta phase. If you look at other meta sites, you will notice there are similar questions.–None–2016-08-24T11:49:02.317
1In fact, the Help Center section I am referring will be editable only from moderators. It will not br edited until the site doesn't reach the public beta phase, when the site will have pro-tempore moderators.–None–2016-08-24T11:53:57.767
I'm going to close this as too broad (for now). See my extended discussion below: http://meta.esperanto.stackexchange.com/questions/15/what-should-the-help-center-say-about-the-questions-we-dont-allow/19#19–None–2016-08-24T14:40:12.973
