My description was oversimplified, there's a little more to them than 
that. Such as name, address, affiliation, comments, flags for 'may the 
signer be contacted' and 'allow signer's name to be public, id of 
petition the signature is related to'. The signatures have no 
behaviours per say, but it will be possible to get stats on # of 
verified, unverified, # per day. There will also be mechanisms for 
printing lists of name/address of verified signers, as well as sending 
one-time reminders to aged, unverified signatures. I'm also loosely 
thinking ahead to methods to send campaign letters and such.

I'm all for bloat-free code and realize I may need to re-think my 
approach. I'm hoping to get off to as good a start as possible.

Thanks for your opinion. It's appreciated and respected. I've tried 
writing both ways, and have read through a lot of other mods. It's good 
to hear the thoughts of others with a deeper experience than my own.
