Features: * for page save, ask a random question * match the given answer against a regular expression * q and a can be configured in the wiki config * multi language support: a user gets a textcha in his language or in language_default or in English (depending on availability of questions/answers for the language) Tips for answering: * you need to answer the textcha for e.g.: * page save * attachment upload * user profile creation * you do not need to answer the textcha for e.g.: * page preview (if you do, it will remember what you entered, though) * user profile changes * it is usually a simple/short answer * it compares case-insensitive * sometimes you can find the right answer by reading some important pages of the wiki == Configuration == Tips for configuration: * have 1 word / 1 number answers * ask questions that normal users of your site are likely to be able to answer * do not ask too hard questions * do not ask "computable" questions, like "1+1" or "2*3" * do not ask too common questions * do not share your questions with other sites / copy questions from other sites (or spammers might try to adapt to this) * you should at least give textchas for 'en' (or for your language_default, if that is not 'en') as this will be used as fallback if !MoinMoin does not find a textcha in the user's language In your wiki config, do something like this: {{{ textchas_disabled_group = u"TrustedEditorGroup" # members of this don't get textchas textchas = { 'en': { # silly english example textchas (do not use them!) u"Enter the first 9 digits of Pi.": ur"3\.14159265", u"What is the opposite of 'day'?": ur"(night|nite)", # ... }, 'de': { # some german textchas u"Gib die ersten 9 Stellen von Pi ein.": ur"3\.14159265", u"Was ist das Gegenteil von 'Tag'?": ur"nacht", # ... }, # you can add more languages if you like } }}}
