I mean in "Forum Profile => signature" so it shows up like mine-- in your signature..

...Good to see the two square holes in your drum as found only on original 2 1/2" Shelby drums. Unless you have pedal pulse, grooves or other issues I would only sand the inside of the drums. No sense in removing any material from these.
Your "Signature" can be added by editing your profile settings.
I agree, machining the drums will remove A LOT MORE material than you think. Bills suggestion is solid. I would hesitate doing it if not absolutely necessary.
