As much as I would like for it be as simple as a plus or minus support it really is more complicated than that.
So far all my experiences with you have been neutral or positive, I would say you are one of the better admins in the current staff team, however that doesn't mean you're ready for lead team. First of all, I would like to mention your somewhat rocky past, I'm not at all aware of what exactly it is that happened but I've heard that you were demoted not too long ago and left on a sour note, you have indeed returned a "better man" so to say but it will still take a while before the lead team can trust you enough. Another important thing is standing out enough, like I said earlier you are one of the better admins on the staff team but you don't stand out enough. As it is currently there is no shortage of lead team members to complete the work if something there is a shortage of work for the lead team to complete which leads to the standards going up and up. I personally believe that if you keep working on improving yourself you will definitely get it sooner than you might think. I hope my criticism isn't too harsh, I am genuinely doing this out love and respect because I want to tell you the hard truth so you can grow from it!
