How did you post if you can't log in?
I'm assuming that you also made the above post, Iron?
Don't worry that the site has glitched; it happens now and then. It's just one of those things. It's happened to me in the past as well. The site seems to sometimes log you out mid-post, so when you click on the post button, your post is registered as being by "Guest" and you cannot edit or delete it since as far as the site cares, someone else made it. Does that make sense?
Oh, and if you don't get the confirmation email, check your spam/filter box as well. I've heard from a number of people where the confirmation emails get diverted to their spam boxes.
If you want to post pictures, the site only supports a few formats. Make sure it is in either .gif .jpg .jpeg or .png. Any other file types such as .bmp are NOT supported, and your image will simply show up as an (Unclickable) link instead.
These file types are the types supported by most picture hosting websites, so it shouldn't cause any problems.
Anyways, welcome to the site.
