// Description:
// * MARK SEMI-AUTOMATICALLY UNSIGNED COMMENTS ON TALK PAGES
// 
// Authors:
// * based on [[user:Olliminatore/unsigned.js]] (old and buggy version 1.3) which was based on [[:en:User:Invitatious/unsigned2.js]].
// * updated/changed by [[user:lustiger_seth|seth]]
//
// New features in this version (compared to [[user:Olliminatore/unsigned.js]]):
// * You can now choose any signature (it doesn't need to be one of the last 10 any longer). Used signatures will be marked. Some bugfixes, see history (here and monobook.js) and talk page.
// * compatible with vector and monobook
