We do not know what interest PowerGlove has right now but most probably it's to gain a good forum rank, have a spot it DT and be a respectable member. Today or tomorrow he will achieve it and then he will have no motive to move further. It's the reality.
He has skills to do SMF patches and he seems to do it comfortably with his understandings on SMF forum software but I really can not go far to say his efforts for forum security and SMF patches to improve community experience is to gain rank, reputation and what's more like a moderator, global moderator position.
Staff position is possible but a global moderator position will need much time for PowerGlove to achieve. Being a technical member with good contribution for the forum is big advantage but theymos will need more time to actually trust PowerGlove and appoint global moderator position to the coder.
