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
