gnus-valid-select-methods

gnus-valid-select-methods is a variable defined in `gnus.el'.
Its value is shown below.

Documentation:
*An alist of valid select methods.
The first element of each list lists should be a string with the name
of the select method. The other elements may be the category of
this method (i. e., `post', `mail', `none' or whatever) or other
properties that this method has (like being respoolable).
If you implement a new select method, all you should have to change is
this variable. I think.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 24.1 of Emacs.
