Tom, I was trying to delete the post but didn't know how. There were no photos, I was simply asking if anyone knew about experimental notes. physics-fan replied with his post so I reposted my question under paper money, then while looking for a way to delete these unnecessary and redundant posts on U.S. Coins, I came across the thread search system and looked for "Experimental Notes" which gave me the answers I was looking for, but I'm still unable to erase these *embarrassing* posts because if you just try to edit and erase them, the system won't let you just save an empty page(after you've erased) so I had to put something on the page, ergo the punctuation marks. So, there's another thread floating around in Paper Money that has the same original posts as this one once did. No sense in trying to erase it, if I just end up having to leave unexplained punctuation marks behind.
I posted something and after doing so I thought it was redundant. I asked one of the moderators to delete the post. His reply was that it was Coin Talk's policy not to delete a post once it's on the site. I forgot the reason given but it did make sense.
If you read the posts in sequence, rather than individual posts, it spells out some pretty nasty swear words: ?!~?! !!?"> /.,<>?,./';": ;($& @-)" I mean, about the only one worse that I can think of is $#%&^@&%^*(!!
