= What is a TextCHA? =
It is a pure text alternative to ''CAPTCHAs''. !MoinMoin uses it to prevent wiki spamming and it has proven to be very effective.

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
