If this isn't attention-whoring, then what is? What it seems like to me is you want one of us to beg you to stay.
Only post threads in this section if you really are going to leave/come. Not asking to see others opinions about yourself.
You've been an active member, on SMP, and if you stay at it you could get your rank back. But leaving now, won't do you any good at all. So I think you should stay. We all make mistakes (I've been banned from lava before). Things happen, but you should be able to get past it.
Someone once said:
Yesterdays history, tomorrows a mystery, today is a gift, thats why they call it the present.
Forgot about what happened before, and go out and be more active, and prove yourself to others, that you can do good. Leaving won't get you anywhere. You'll actually regret it in the near future. So, stay, and work even harder than before and redeem yourself.
