If you want to check your mana and voting power use steemd.com/@yourusername ie mine is https://steemd.com/@felt.buzz
My mana is around 25% full. I'm not sure how much this post will cost, but I have posted two comments and they cost me half a percent each. I think it will vary per person so you'll need to check for yourself.
edit: so posting didn't seem to use up much mana, commenting used more. I understand that posting adds more value to the blockchain, but it will be a shame if newbies can't comment as much. It was one way they could engage with more established people and get noticed and helped. I hope this doesn't have an impact on growth.
So this will be my last post or comment until I am powered up again, because I don't see the point of arsing about for days on low voting power and posting power - it will just prolong the agony!
I'll be watching to see what you all get up to, just don't expect any votes or interaction from me (although you can find me on discord if you need to).
Big love and stay strong!
