Don't ask to ask. Just ask the question you want an answer to quickly and concisely, and if anyone knows, they'll reply. Make sure to stick around so your question can be seen and replied to. See http://www.catb.org/~esr/faqs/smart-questions.html | If no one replies, try asking someoned voiced or oped.
