Thank you for your reply, Fool Zero. I have ensured my browser allows cookies, and everything else you mentioned is good to go on my end. This is the first time I've been logged out so frequently; the anomalous nature of the recurrence is what made me think something may be awry! I shall double-check to make sure nothing on my laptop is impeding my stays on the site.
Thank you for taking the time to address this concern, I do appreciate it!
