Well i guess you've already got the idea what i am going to say from the title. We need 2 different forum sections for application and training. Because lets consider if someone wants to join your clan once it is approved. Clan has different options once is accepted such as setting someone as recruit or a member let me add, Recruit can't have the clan tag they are beta members xD. So if someone wants to join the clan they can directly request to join. I think you should make an application section to know about someone his complete intellectualism, Their behaviour, Background, age etc. So it goes from complete process and people should vote for them either they can join or no.
Now about Training section, Obviously no clan has ever been without their trainees, People in your clan like Chris is a good player. He can train middle orders to get better ranks and better gaming skillz, you can consider me aswell for training i can give as much time as possible although it is going to be hard for me after tomorrow. But i will try anyways, If anyone needs help about particular skillz or complete training they can post and select their trainers. If i am missing anything i will surely add in the reply, Thanks!
