OOH! And you have a Manhunter icon! Sweet.
First of all, welcome! I see you're an Oracle fan. You'll do juuuuust fine :)
If you want to post, hit "User Info" at the top, then hit "Post". Make sure you've joined the community, and at the top of the page, click the Post To Daily Scans option. Type your contents, and to post an image, upload it to an image hosting site such as PhotoBucket. Just above the box where you type everything, 10 from the left on the tool bar, there's an icon, click on it, paste the image url, and then it'll appear in your box! Make sure you put it behind an LJ cut if your image is larger then 300x400 pixels. To make a cut, highlight everything you want in the post, and hit the button three to the right of the image button.
