I have a blog that I believe was created in some format of wordpress.org (I only know this because when I log in to make posts, under the WordPress icon it says WordPress.org). It was previously created by a web designer who has been non-respondent when I need changes. So in my attempt to get this project complete, I was going to purchase a premium theme and I thought maybe I could somehow transfer over the old site info to the new one. But I'm not sure if that can be done or if there's an easy way to do it. (If I can't then starting from scratch is something I will do).
I have my log-in information to add posts, navigation etc but I'm really not familiar with this process at all.
What I planned on doing was paying for the premium theme but I'm not sure if I can add a post slider to the design because it's not listed. Is that something that can be added even if the theme (Magazine - the one with Lenny Kravitz) doesn't actually have it? Can I add some kind of widget or plugin or something to that theme? That's the only feature the theme doesn't have that I would really like.
