Amelia, it'll be nice if you could have one in the regular OP and then a special one for the celebration OP but I'd say that it's up to you to choose where you want it to be placed (if you write only one
).
But the content is slightly different (I would say) ... since the regular one is more of why you love Bellarke and other general comments on them, whereas the celebration one will be more for this thread ... like why you love the thread/something about the 200th celebration.
