I managed to resolved my cookie-trouble
I had accidentally blocked all cookies for community.livejournal.com and skater_g8r.livejournal.com (that's why I couldn't comment on ds_harlequin and ds_flashfiction - and why I've been ignoring ignoring you lately - sorry, skater_g8r), but I got it all set now! *takes a deeeeeeeeeep breath*
