I hope. I'm waiting for replies from two professors I emailed asking about advice for a PhD and how to pursue it. I even included my proposal and how I'd go about it. One of them, at least, mentioned taking PhD students and the other is at the school that'd be best for it (due to proximity to where I'd be doing field work). Both mentioned a research interest in the topic too. I even emailed from another university in the country's account.

I've also emailed another academic over a month ago about an article he wrote abiut a type of non-profit I'd love to set up, and haven't heard back. Though when I emailed him last year it did take 6 weeks to respond. I just wrote this to say I feel it's very hit or miss, depending on the academic in question.
