Its not about being "funny" as we all spell things wrongly sometimes, accidently. When a whole paragraph is full of spelling mistakes with words spelt as they sound, it makes it very hard to read.
Think about it, why do you make a post on a forum. Normally because you have information to share/contribute to a thread, to whore or just to chat. If people cannot understand it, it becomes pointless posting.
I don't like to use Brentton as an example as he has been the person doing the most outside of the club to organise events, which is a credit to him but if he is posting locations/directions and meet details, they need to be spelt correctly.
This isnt a dig at the ability to spell as we all have weaknesses but when anyone makes a post on a forum, it is for the benefit of other readers.
With a built in spell checker, it makes it even easier to check now.
