Help:Signing contributions
From SCWiki
It is normal to stamp any contributions to a talk page (the one under the discussion tab of every page) with your username and if appropriate, the time.
All you have to do is this:
~~~ to stamp your username ~~~~ to stamp username, time and date ~~~~~ to stamp the time only
As a general rule, you should not stamp contributions on main pages that are not fully attributable to yourself. An article or news item would be fine, but a change to a crag page would not.
