Part of this collaboration is organized by us: maths online is used in a number of school classes and courses for adults' education (see Collaborators). All those using maths online and not (yet) being in contant with us are invited to send us their experience, critique and suggestions. On demand, contributions will be published here.

You can send us a message by E-mail or web page form, snail-mail, fax, or give us a call (see Authors).
