Clans who feel frustrated for not appearing can edit the map and add themselves :p
There shouldn´t be any clan frustrated about being absent:
http://openarena.ws/board/index.php?topic=3981(and i am realy sure about the fact, that you will remember the topic
)
Included clans are this one, who had given a response to my request...
Anyway: if there is a clan, who likes to have his logo in this map, feel free to contact me. I will see, what i can do.
Maybe a shader like the shaders used for the flames could be a solution if many clans give an answer here...
