I remember trying to access a database outside of joomla . I posted on J.org and was surprised that the only response was from a guy that didn't know. I never did figure it out and instead imported the database into the joomla one, which meant the component was off no use other than to myself.
I'm guessing most of the issues would be of a similar nature since it's unlikely that a potential student like myself would have issues too complex, and I'm sure it could provide good reading material.
Love this idea. Would you please repost it in the Learning Group? Maybe we can do a better job of getting attention on it. We are closing the home page forums for simplification. Thanks!
