nHowdy and welcome! I saw your change regarding the border Norrland/Finland, and I know I had a source for that... but I'll dig it up later. We'll take that on the article talk page, when I find put what source I used.
These are a couple of links that people like to give to beginners. You are in no way expected to read all of them right away, but you can leave them here and check when then you feel like it.
Also, a link to the page about Wikipedia policy might come in handy sometimes.
On talk pages, such as this one, one should sign ones name using four tildes (~~~~); this will automatically produce your name and the date. If you need help, you can check out Wikipedia:Questions, ask me on my talk page (or someone else, of course) or place {{helpme}} on your talk page which will make someone show up shortly to answer your questions.
Happy editing! // Habj 01:34, 30 May 2006 (UTC)
