Institutional subscriptions are available at the prices below (quoted in U.S. dollars) payable with bank transfers or credit cards. After paying with bank transfer, please, scan the bank receipt and send it out to rwctweb@ct-net.net together with your IP range data.
For paying with credit card, click your option right in the table below and proceed.
Schools, libraries and other institutions can subscribe to online issues of Thinking Classroom using their IP address range. In that case subscribers will be authorized on this site immediately if their IP address corresponds to the IP address range they specified when subscribing.
IP range subscription is available for the prices below to a single block of IP addresses not exceeding the total of 255 (C subnet). A greater range may be served in case it is assigned to the subscribing institution according to the RIPE base.
The amount of simultaneous IP sessions from one IP address is limited to 10. One session lasts for 30 minutes. After the session is closed you have to wait 5 minutes before next session.
You may subscribe at any moment, either for the current or for the upcoming subscription year (you will let us know of your preference by sending a message to rwctweb@ct-net.net). Online access starts either immediately (for the current year) or in January and expires on Dec 31 of the subscription year.
