I try to proofread every post/PM I make. From time to time, I notice a mistake after I posted my message, but thankfully we're able to edit our posts here.
I've noticed, but you don't do it very often. No one is perfect with it, and there will be the odd mistake that finds its way in. I'm more worried about some of the people that can't seem to spell all the time!
I called, but their voice message said there wasn't any tennis tonight. Therefore, pretty open night tonight. I'll be heading off at 6 for supper, but I'll be back later on tonight.
