Forum:I'm new and confused

I've been editing wikis that already exist for a while now, so I thought I'd try to make a new wiki about Jasper Fforde, and now I'm stuck. For starters, I dont have a clue about how to make the wiki the usual format, as opposed to the one it started out with (navigation bar, logo, full page ect) and, probably related to problem one, I can't upload a logo, no matter what I try. I have loads ideas about what to put in the wiki itself, but no idea how to start. HELP!

Yay, I figured number one out- I changed the skin, duh! Any ideas about number two? 'The file is corrupt or has an incorrect extension. Please check the file and upload again.' Amthysteyes2 13:33, 30 August 2007 (UTC)


 * Just letting you know, the skin is a per-user setting, so most new users will see the quartz skin when they visit your site. That might affect some of your page design decisions.  As for number 2, my bet is the image you use has an incorrect extension, or doesn't have an extension at all. -Afker 15:37, 30 August 2007 (UTC)
 * If you want to change your logo. It has to be a .png file and the destination file name should be Wiki.png. The new skins also have a wide version that you can save to at Wiki_wide.png. I'm assuming your a sysop on your local Wikia. Otherwise, you do know (or should know) that you can't change the logo yourself.--Imaginationac (Talk) (Edits) (Email) (Aselia, the Tales wiki) (Tabula Rasa Wikia) 17:25, 30 August 2007 (UTC)


 * Thanks, but I already knew about the .png stuff, and I dont know what an extension is.
