1.  Moderation can take up to 5 business days.  This is the extreme case, but it does happen sometimes.  Saturday & Sunday are not business days.  If you submit at 7pm on a Friday night, there's a chance it won't be seen until Monday.

2.  If you "found something on the Internet" and do not provide proper credit or permission, the item will typically be rejected.  We accept original work, or work that you have permission to reuse/redistribute.  If you don't have permission, it is considered ripping.  It doesn't matter if you couldn't find the original author.

3.  If there is question over the source of work in the moderation queue, all work by the author is held while the matter is looked into.  So if you submit to multiple galleries, and we find something suspect about one item, all submissions are temporarily on-hold until we can resolve the issue.  (This was the case with AzDude's original post)

ioniangod21:
There are only two uploads recorded to your name in the Dream gallery.  We can see items that have been posted, rejected, deleted by user etc.  The other 8 you say you uploaded probably encountered an error and never made it in.  Your two items were rejected because they didn't meet requirement #2.
