No. I use MA as a fact-checking resource if I want to double check a stardate or the shooting date of a particular episode, but editing in stuff myself only to have it inevitably changed by some other user or an admin just sounds like an exercise in frustration, especially if they're changing correct information to be wrong once again. MB I use even less, and I've heard a few horror stories here about the admins there abusing their power.
I'd rather just have (relatively) friendly debates here and on Twitter, or else do my own Trek stuff like my Timeline (here's
the 23rd Century and here's
the 24th Century) where I can have the last word.
