@Lockdownbear if you're an arm chair scientist / know it all then yes I'm having a dig at you. If not, then no I'm not.
Spelling is not a sign of intelligence but if Scotsnet has taught me anything then you don't need a good reason to be a snidey bastard about folk. See just about every comment on this thread about Nicola Sturgeon as examples.
And while it's not a sign of intelligence it does grate a bit the constant misspellings of your/ you're and there/ their/ they're from people getting all judgemental on their high horse.
