Hmm, well, this is just a suggestion so you do not need to do this if you so wish. Though, there is a way of uploading your picture on Photobucket into your post by modifying it. Just copy the photo's URL and use the code below to embed it into your post:
[IMG]-Insert photo's URL here.-[/IMG]
Since your photo is already uploaded on Photobucket, just right click and there should be an option that says 'copy image URL'. Just click that then use the copied URL in the code above. It should work then.
Though, I have viewed the photo and I have to say, great work. I hope to see more from you in the future. It's pretty good for a member who has just joined.
Also, to answer your other two questions, you can give floofs once you become a Jr. Member, which is when you've posted 25 posts. So you're nearly there!
A Floof-O-Meter is similar to Karma on other websites. When you, or anyone else, views that a particular member has helped around the forums and done some positive hard work, they give that member a floof. Like a reward, per say.
Lovely beginning maps, floof ^^ Can't wait to see more from you in the future, and I wish you the best of luck in your map making!
