Pinging a website?

Hi,

Im using comments as a way to build backlinks, and many people say after you have commented a page you should ping it to speed up the indexing, but what software/service do you use to ping a page? I havel ooked at pingoat but you can only ping every so often.

Is there any software that you can load a list of urls into and it will ping them all?

Thanks

Here is a list of urls you can use to ping I was using this for my blogs, these are full urls I think there is no problem in posting them as is here..?
