Well, I did a few updates to the backend of the site, mainly to the way the images are handled and the registration process. You shouldn't notice any differences, but if you are having any problems with either registering or uploading pictures, let me know so I can look into it further.
I also changed the post length from 45 days to 90 days about a week ago. If you have a post that is live, you can simply wait until it expires, then edit that post and re-publish it which will keep it live for an additional 90 days.
