I must admit that some posts with nothing more that just a link or a "telegraph style" are not always self-explanatory, but when it comes to say hello is nice to see the word count was lowered because ten words were too much
Surely you dont just want to put 'hi' in a post.
I never post one word posts it doesnt help anyone else follow on from the post and it doesnt make the person above want to respond.
Maybe a quick hi and welcome to to the forum would be nice etc.
That way it makes the original poster say thank you etc.
