group control

How do you add entries to existing groups???
It seems that inserts replaces the grolist completly.

I'm using perl to extract the whole grolist, add to it as a perl list
then replace it in the db using an insert command. Is there a better
way, if so what's the systax.

My intention is control student access using group permissions - is this
resonable??

Are there limitations on the size of the grolist??
