Hi Gunter , sorry to hear you're having troubles getting established - you've arrived in an interesting period for steem(it) with a whole lot of people joining at once.
I'd recommend just focussing on building your followers by engaging with other peoples content, and getting involved with groups like minnowsupport and networking.
I'm following you now and have voted some of your past posts :)
For your error, I delegated a little extra SP to your account temporarily and a more permanent fix is happening already : https://steemit.com/witness-category/@blueorgy/witness-consensus-reached-for-maximum-block-size-with-a-median-of-98304
Best of luck
Great reply ausbitbank - appreciated you dropping in and paying a visit. And important thread I believe. Both strategically speaking and with respect to setting steemit expectations. SK.
