Also unsure if this is the appropriate place to put questions, but I'll put it here:
This is my first conference. I haven't received any emails concerning Swapcard – was I supposed to? The acceptance email did not mention it.
I filled out the form. It was mildly annoying to write down the channels/newsletters I regularly watched/read, since the text cursor would return to the beginning of the textbox if I went to a new tab. It's a minor problem, though. I believe this has to do with the fact that the form has "Short answer" questions, rather than the "Paragraph" question. I suggest having the latter next time, since it mean that the annoying behavior above does not occur. Also, it means that I can separate the names using line breaks, rather than using commas and spaces (which is what I did).
