i need to know how to be Clan member in CSBLACKDEVIL COMMUNITY Which is in game tracker http://www.gametracker.com/clan/CSBD/?membrspge=2#membrs .

At the bottom of the CLAN MEMBERS block, there is an APPLY button. That will apply for membership into the clan page. You can find admins by looking at the titles of users in that page and send them a message if you want. Generally, the higher ups are at the beginning.
