how does this tag system work what type of script or code you need to do something like this ?

From what I can tell from glancing at it, you're supposed to put that tag on each of those services and I guess their bots scan/search the sites for that hash tag and then publish it on their own site.

I'd bet it's a custom script. I've never heard of anything like that before.

ok ...

so anyone know

epitome seems right

ok cool cool anyone here can do such thing

it uses an obscure tag, so not many people will use it, and that way they can query the tag content for the event page.

if it had a tag like #celebs it would be cluttered.

so fris is this some type of plugin of wordpress

probably just some sort of work with the youtube and twitter ip that grabs the tags in question and adds to the event wall/list
