I am a member of a small 10 man semi-casual raiding guild and throughout WotLK we ran into problem when people were unable to make raids, because we just weren't big enough to replace them. So the officers have decided that we needed to fill our guild with people for cataclysm. Currently we are not targeting any group in particular (we will take any level, any class, any spec). Today I made an effort to try to get some new members, but was rather unsuccessful. I mainly tried spamming (yeah I know I hate to do it) in both trade and guild recruitment channels for new members, but I am unsure of what else to really do.
So my question as the title says what is the best method for recruiting?
