Sounds like you have a caching problem, Danni, 'cause your posts seem to be coming through just fine. You're just not seeing them immediately because either your browser or your ISP is sending you a copy of the old page.
Try holding down the Shift key and then clicking on either Reload or Refresh (Netscape or IE). If that works then the problem is your browser and you'll have to adjust your options in it. If that still doesn't work the problem is with your ISP. And your only option is to talk to them and tell them you need caching turned off.
Hope that helps!
