# How can I upvote a comment again?

By mistake I double voted a comment in How to evaluate $\int_{0}^{\infty} \frac{x^{-\mathfrak{i}a}}{x^2+bx+1} \,\mathrm{d}x$ using complex analysis?, and now I can no longer restore my upvote. Is there anything I can do other than be more careful next time?

Background: I made the mistake because I got out of sync, my phone was slow to respond to the first click prompting me to try another. Maybe set up a time limit to decide either way?

• I retagged support as I got the impression you are more inquiring about the current situation than trying to propose a change. – quid Nov 24 '17 at 21:22
