Update Services

vBseo's ping trackback feature is great. Also there is another section where we can ping automatically.
http://rpc.pingomatic.com
http://rpc.technorati.com/rpc/ping
is already been pinged automatically by vbseo's settings. I searched around and found another one Blogs Trend Tool - IceRocket
Does anyone knows any other places we can ping everyday ?

Here is a complete collection;
Update Services « WordPress Codex

However, this is really unsuitable for forums, which will be handlings lots of new posts and threads daily unlike that of blogs. There is however a more concise list of update services you can checkout.

Although, i do have an issue with pinging both Technorati and Ping-O-Matic. This is because, within Ping-O-Matic you are sending a ping to numerous services, including Technorati. Therefore sort of reducing the neccessity to ping Technorati individually in the first place.
