Page 146 - 42 Rules for 24-Hour Success on LinkedIn: Practical ideas to help you quickly achieve your desired business success.

Please note that questions that simply ask for in-
troductions etc., usually don't get answered but
they do get flagged. If a question receives several
flags, it is removed and users who have several
flagged questions may lose the right to post any
additional questions.
Once your question is written, you select whether
or not you want people outside your network to see
the question. Unless you have a geographical-
ly-specific question, it's probably better to allow
anyone to respond, as this will probably result in
more responses.
The next section in the asking question process
labeled "Add Details" is optional. If you have more
clarifying details or content to add, this is the place
to do it. Again, try to bullet point your thoughts.
Keep your sentences short and make sure you're
only supplying relevant detail necessary for
someone to best answer your question. You may
want to have a friend or colleague review what
you've written to make sure it's understandable.
Once you've completed this, you are asked to Cat-
egorize Your Question in one of 20+ business cat-
egories. After you select a category, you can
further refine it by selecting a sub-category that
best relates to the topic of your question.
You can then select geography as a further refine-
ment if that is relevant to the information you're
seeking. You can select by country or zip code.
