- Questions regarding Q&A Plug-in - 1) Displaying

Hi – Questions regarding Q&A Plug-in -

1) Displaying on the homepage - I created a sub domain specifically for the Q&A section, and would like to display it on http://ask.beautyglimpse.com. However its currently being displayed at http://www.beautyglimpse.com/questions/ask/. How do I fix it ?

2) Height of the textarea - How do I reduce the height of the textarea box across the site (Just below the “Title:”)?

3) Permalink Structure - I have opted for http://ask.beautyglimpse.com/%postname%/
What happens when users post same questions twice (i.e. same /%postname%/)
Will the system make necessary adjustments ?

Thanks in Advance.
