 == Category:Wikipedian aikidoka == 

 Hi there Peter. Thanks for creating this category and for your other work on Aikido topics. I'll tell my co-worker to put himself in it. However, since it is a self-reference to Wikipedia (like all categories under Category:Wikipedians), it should not be used in the main namespace. Thus, I've removed it from List of aikidoka. See Wikipedia:Avoid self-reference for more information. You might want to put a note on Talk:List of aikidoka to direct interested Wikipedians to put themselves in the category. You can use  to make it stand out, like this: 

 This article is for well-known aikidoka. To add yourself to the list of Wikipedian aikidoka, add: 
 : [[Category:Wikipedian aikidoka|{{PAGENAME}}]] 
 to your user page. 

 Thanks again.  "
