Source code

Source code is text and characters that humans write in order to tell your computer and mobile phone what they should be doing.

Talkyard was previously named EffectiveDiscussions. All source code uses the name EffectiveDiscussions or ed-(something), until we've had time to rename to Talkyard. Debiki is the name of the company that builds Talkyard.


A source code license is a legal text that tells people what they may do with the source code, for example, edit it, use it, give it away to others.

Currently Talkyard is licensed under the GNU Affero General Public License, which means that it's open source and that you can download Talkyard, use it, modify it and share it with others — as long as you share alike your modifications.

Please let me know if you want me to change from AGPL to GPL.
