Member Phone Number format
The phone# validation rules are configurable. I took a guess and setup like we have it for our 90% 614 area code, but some churches are between zones and have significant variation - so we can easily require the full 10 digits for everyone, with whatever input "mask" (parenthesis or spaces as delimiters) you prefer. Not a problem at all - just a config item in the system profile I use to (re)build your website and database.
Check the internal codes for PHONE_xxx - these are mostly self explanitory.
Also, only set the AREA_CODE value if you are using a pair of short and long patterns (one with area code, one without). Otherwise, if you just have 999-999-9999, local phones can get rejected.
