Technical difficulties??

I am having trouble posting comments on all blogs that use Word Press as a host. I cannot figure out why but they just don't show up. I have tried three different browsers and still nothing. Of course I am only currently using my one laptop because I haven't had a chance to try it on a different one, but I was wondering if anyone else out there was having this same problem? Maybe its the way my computer is configured?? In any case, I wanted to leave a message to all of my Word Press blogger friends who I tried to post a comment to from the past few days. Just know that I was not ignoring you but I was unable to comment. This includes Stacy, Kim, and Sarcastic Mom as well as many others whom I have visited but couldn't post. I hope to get this fixed soon cause its really annoying! If anyone has any clue as to why I am having this issue, please leave me a note. Thanks.
