I have a question about PayPal and what just striked me, is that if it wouldn't be PayPal, where would I ask questions about websites and web-services? On "WebApps" it is not allowed, because there I am only allowed to ask about websites that "behave like applications"?
So as I assume I cannot ask on "Webapps"(.stackexchange.com), how about "Personal Finance and Money"? Sounds good to me, but: I basically want to open either a "Premier" (individual who sells) or "Business" (merchant) account with PayPal, so my questions are actually all about that, about the prerequisites, fee structure, obligations etc. So that is not exactly "personal finance" anymore and very specifically tailored to PayPal. If you look at this case, where on stack exchange would you ask?
