I need a guestbook-like script that will provide the same range of features of something like: [login to view URL] or [login to view URL] as well as a few more. This will be a charge per post page, and therefore I have a couple of additional needs: 1) Will need to charge per post, I will be using [login to view URL]'s shopping cart or/and paypal charges will be based on 1 of 3 posting lengths and how many years it is to remail in the database (1-10 at this time). 2) I need to be able to give clients 3 leves of post lengths in either lines or characters (pref characters) which I can easily set. 3) I need to be able to ask my posters how many years they will want the post to be up for (say, 1-10) and have that be part of what is emailed to me. 4) I need to make sure I am notified of new posts and keep them offline until I approve them. 5) I need to be able to see posts by month, and will hear your suggestions on whether a little calendar or menu bar is possible in order to this easily. 6) I need to be able to ask my posters how many years they will want the post to be up for (say, 1-10) and have that be part of what is emailed to me. 7) I need to be able to be able to erase posts older than x years either when I choose to, or automatically if possible and if it does not make things too complicated.
