Also how do you post pictures in a post. I have looked through the forum and can't find anything.
Upload your photos to a picture site like Photobucket, and then to put them into your posts as clickable thumbnails, the formatting is as follows (with props to SKEETERGOD who showed me how to do this):
[ url=www.photo.com/myphoto1.jpg ][ IMG ]
www.photo.com/th_myphoto1.jpg [ /img ][ /url ]
You need to add "th_" to the start of the actual filename in the IMG tags, but not in the URL tags. Don't worry about renaming the photo, this is just telling the computer that you want a thumbnail. And obviously I've typed it with extra spaces so you can see what's going on, you don't need these for your actual pictures.
The best way to check if anything isn't working is to use the Preview button when you've finished your post, and check that everything's looking ok.
