Well… with 301 redirect, http no longer exist (sort of) so no worries about duplicate content. The hardest part is making wordpress work with ssl – once thats done your set!

Matthew is correct, but assuming you wanted to turn your computer into a web server could be (difficult, but) possible.

Hmmm… I am not sure about wordpress’s compatibility with addon domains with wildcard dns. Not something I’ve come across. Also, if you have only recently added the wildcard maybe Prorogation time has something to say with it? Once again, not sure and another users confirmation would be good!

Yep. Contact Yahoo. They can solve it.

I’m not quite sure which one you are talking about. If its an uploaded image from your computer then you need to update the image on your computer then re-upload. Please try to be specific. Hope this helps.

You probably have done this but have you gone into Network Administrator > Themes > Activate desired theme . Back to your main site dashboard > Themes
