Garinda's right.We all have our own personal bugbears.Mine is poor spelling/punctuation in posts but I realise it's not a strong point for some people so I wouldn't pass comment.A thread is like a conversation,ie a comment here,a joke there and we're soon back on topic.As Westender said,it would indeed be a dull site if we stuck rigidly to the thread title.For example,someone asks for tips on losing weight.After person one has replied eat less and person two has replied get more exercise,without being allowed to deviate at all,what else is there to say? Threads would only be about 3 posts long!
Get yourself a sense of humour and have a laugh.Go on,startle yourself and make a witty remark.I'm sure you've got one in you somewhere.
