What about the values? Say my form-specific value was set to 1, but I make the default value of the base class be 0. Will the 1 still be honored?

Also, what about methods? I have begun to add a certain method and code in to almost every form, so now I want to go back and stub in the method name in the base class, but it will not have any code. Do you think this mess up the existing method code in the forms?

I did not realise I was going to want it everywhere, but now I see that I do. The code won't be in the baseclass, but I was hoping to get the method name there, with comments, without losing all the method code I have already placed in the forms.
