Post about information so:
-What the clan does
-Activities the community might do
-Why it is so fun?
Then How to app:
-Your expectations
-What is the minimum
-Are the sections (Building, eventing, scripting... etc)
Then if you get so far:
-Clan projects
-How people can pitch in
Just a few suggestions. Just try getting some more stuff into it and maybe, you never know, this clan could take off! It's all how you take this first step! :)
