What do people think? IANAL but I'd have thought a statement such as I suggested would constitute a copyright licence in itself and that people contributing materials would by doing so accept their contributions being used under a subsequently-decided licence (with the option of using the wiki to edit out their work from the 'current edition' as it were, if they wanted).
That would still leave the question of existing contributions i.e. before we apply any licence. Some contributors are known and their agreement could be sought. All are, presumably, readers of uk.d-i-y and likely to follow discussions there: would discussion in the group be 'reasonable' notice that a licence is being applied and warning that if they're unhappy they should get the system administrator to pull their stuff?
And what is the legal position of stuff contributed anonymously i.e. when the wiki 'user' is recorded as an IP address rather than a registered user name? Presumably in practical terms it would be hard enough for any individual to lay claim to content attributed to an address that (for the value of text already in the wiki) it could be discounted?
