Please let me know if I can help (I have posted on some do's and don'ts, although it is quite a ways down in my many blogs, mine and resteemed ones).
on SP:@ceres.outpost - thanks for your upvote! However, it would help if you understand more about these things, SP and bandwidth, before you go too far into depleting them.
- one vote depletes 2%
- SP regeneration is 20% per day
- power / impact (if high enough SP) is proportional to the effective SP at the time of voting (up or down)
All the best!
