uploading themes from pc to the site

I have a theme that I have downloaded in my PC. Now I want to upload it in my site. Is it possible.If so can anybody please teach me how to do that. Thank u in advance.

You can only import themes that have bbtheme format. If the theme you downloaded doesn't have this format then you can't import it, but you can manually change the buttons, icons, etc. form your forum to the one's that theme has.

But what if we have[i] our file in the bbtheme format?

If you have the file in bbtheme format then you need to go to admin panel=>Styles=>Choose your style=>Management and from the "Import it" section click on "Browse" button and search your PC for the bbtheme file and then click the "Import" button.

I don't see anything related to 'Choose your style' in the styles tab

aha i see nevermind
