(something), which (clause)

Use the word "which" to add an extra description of something:

I'm the creator of the Women's International Network, which is a networking group for female professionals around the world.

Notice that there's a comma before "which". This shows that you're giving extra information. The listener doesn't need this information to figure out which network you're talking about.

If you're talking about a person, don't use "which". Use "who".
