I appreciate you taking the time to answer my question. I'm confused by the following thing, however: when I read other people's comments, when they refer to someone else with a @soandso, you can click on that text to access their profile. When I type @soandso, it is just text that doesn't link anywhere. Is there some technical wizardry going on (e.g. typing something like <a>@soandso</a>)? Do you need an imgur Pro account to do this? I feel like everyone knows but I don't. Thanks again for the help!
