Reminder: you can sort searches by a specific pairing even if there's no tag for it, provided it's been searched for, by combining two /other pairing tags, e.g. Artie/other + Puck/other, Artie/other + Kurt/other. If only one of the characters from the pairing has an /other tag then the pairing you're after will be listed only under that one tag (if it's been searched for already, natch).
There's also a new theme tag, unrequited: for all your one sided, pining and UST related needs. :-)
I'll also be adding in the next few days 'theme: misunderstanding' and 'theme: character bashing'; stay tuned.
Help finding more posts for these three new themes would be muchly appreciated!
