This template is often used on talk pages to show clearly that a section of discussion has been resolved, so that each editor does not have to re-read the section. Its counterpart is {{You're welcome}}.
Placing {{Thank you}} on a talk page makes the following appear:
{{Thank You IP}} – A special thank you for your help in our battle against vandalism. Thank you so much for your efforts to improve this encyclopedia, and welcome to Wikipedia! ~~~ ~~~~~
Any of the following inline, comment-level templates can be converted into {{Resolved}}-style hatnotes by using {{Resbox}} to put a box around the icon and text.
{{enUici|Wikipedia:List of discussion templates|List of discussion templates]], a more linear table of essentially the same set of templates
Template:Resolved/See also, the smaller family of thread-level hatnote templates, similar to the above but with a box around them; any template above can be converted to one of those with {{Resbox}}
