The module I'm working is strickly for a business listing so site owners can offer they're users a phone directory of local businesses and possibly generate revenue from those businesses.
It looks like you are creating a really nice personal/public address book. I would keep working on it to offer the XOOPS community an alternative to the xDirectory. I'm sure everyone would agree.
It's nice to have choices! right now we have some nice choices with calendars and content modules. Keep Programming!
Cheers!
