Personal Contact SELECTED BY DEFAULT, even MANDATED

In community projects it is often the case that members are not really up for reading everything carefully. Upshot - they miss the box and wonder why no one contacts them..., so I'd like to be able to set Personal Contact ON by Default. (User can disable if they wish).

I'd also like an option to MANDATE it so it can't be disabled by user, (People get annoyed if they can't contact a provocative poster).

Note - I went looking for this and found threads in which people who needed this function had posted mod hacks to do it. Which I won't use - too hairy - but shows how important it is.

General Comment - this is a Usability Issue - a key role of Admin should be to ensure that member defaults are designed to minimise the work that work that members need to do, so any check box that it is expected peoiple will tick, should be defaultable ticked.
