I dig it. The pictures look pretty sweet and this sounds like a nice build to watch.
As for posting pictures I have used both ways and I tend to like using an offshore rig, photobucket is what I use.
For using photobucket the process is pretty straight forward, upload the pictures, once you log into your account, there is a button that says upload. Then once you have them in your album, there is a little tag at the very bottom that says copy, it is that very bottom one I know, anyway, just click that and it will copy the url link then just come over to your post and click paste and it will paste the url into your post and when you preview the post it should show it. It also will resize them if they are big to a reasonable size.
Other photo programs are probably different. It took me a bit of work to upload direct to MUD and that is why I tend to lean toward the bucket.
As far as deleting posts, try clicking on the edit tab at the bottom of one of your posts, a small delete button will appear in the bottom right corner of the edit window, that may work. I don't know myself because I haven't ever tried it.
Oh and Welcome to MUD..
