Well it took some patience, but almost everyone who uses the voting bots went to bed finally! Three rounds of 2.5 hours of waiting and I got the bot I wanted, and it did pay off.

I used jerrybanfield's bot and put 5 SBD on it. (So all together I wound up putting in 3 SBD instead of just the 2.) It increased the value of the Logo Contest post by $11.89 and brought its current total to $29.32. Hopefully it can grow a bit more between now and when it closes.

Here are some screenshots from the bid.
