I'm new to hash tables, I know to use hadd hdel $hget, but what should i do to save my hash table on exit and set it on start? I mean all my data will be saved in a hash table, and I want it to be always there -without using -m flag- cos it'll be always there.

What's the best way to use regex for bad word detection, I mean $regex($1-,badword1|badword2) is just too simple and sometimes it is not working as it is supposed to do? What would you use for your bad word detection?

Hope you get me.
