BuddyPress.org

So I’m fairly new to both WordPress and BuddyPress, but I do have some general experience with php and other scripting and programming languages.

I want to do two things:

1) When a group is created: Execute some php script I have written to create and modify some text files.

2) Within the newly created group add some html and javascript code from the text files.

I’m honestly confused on how to do these two things, even after spending a couple of hours digging through information. Am I suppose to implement a do_action or apply_filters? Both of them are a little confusing to me…

Any direction is very much appreciated!

Thanks,
