Sitemap Generator Forum

I am completely new to this website, and trying to put the sitemap I'd just had made to my forums site through InvisionFree. I have a few questions.

1) Where exactly would I be able to place my sitemap? I mean, I'm admin of my own forum (Graphics Haven), but InvisionFree is run by many more people than myself. I can't place it in my board wrapper.

2) Exactly HOW would I be able to create a new 'holder' for my sitemap to upload to my site?

I swear, I think they really should make a sitemap site for absolute dummies like myself.

Hello,

xml sitemap must be uploaded to the topmost folder in your domain.
For instance, if you are indexing the forum [ External links are visible to logged in users only ] then sitemap would be [ External links are visible to logged in users only ]
