I think MRc have enough admins, but must understand, that this is also just hobby for us and noone is paid for being online on servers like on shifts with 24/7 coverage. There is not possible to have all the time someone on server.
Your idea to make someone with high rank an limited admin will be pointless, because he also is offline and there can be also gap when noone will Online from MRc admins and this "external" admins. Also cant make admin everyone. It could make even more worse situations with kicking/banning people from servers by drivers which are not even in a team.
Many admins is same bad option than none admin I think. We as MRc have around 100 admins and I think its more than enough.
Would be good to have voting for kick/ban allowed just for example for drivers with minimum 80% of rate, or at least 5000 points on server, but I have no information about this feature in our tracker yet.
Only way how we can handle it now, is this forum. I know that its annoying if some bunch of stupid kids ban you from server for nothing.
Please write here as you did now and ask for unban and in the best case, attach link with uploaded replay so we can valid your complain.
If everything will OK, we will unban you ASAP.
