I run an online music magazine here.
Some time ago, I'd integrated it with WordPress, and things were working fine. I tried to implement my own theme as well (a little later, the 're-design' mentioned in that link), but soon got frustrated due to problems with the cache on WordPress, and also because the theme kept reverting to the default WordPress theme. Due to a tight deadline, I had to uninstall WordPress, and revert to using 'vanilla PHP' (or whatever).
I have taken some time to go through these forums, and I found some solutions to the cache problem, so I've decided to use WordPress again for the site.
I have just some questions, though.
 I still have the old database from the first install (even though I uninstalled WordPress, I retained the database). If I install WordPress now, can I configure it to use the old database, so that I won't have to copy-paste all the articles and comments again?
 If I do a fresh install of WordPress, what happens to all my article dates? Do the dates of all previous articles get changed to the date that I install WordPress? Is there any way I can manipulate dates in MySQL/phpMyAdmin?
Thank you for taking the time to go through this post, and I would really appreciate any help that I get on this.
