Wikipedia:Please don't shout

He says, "PLEASE DON'T SHOUT"

Article talk and user talk pages are places to interact with other users. As in real conversation, there is etiquette that should be observed, to make the dialogue more friendly.

Typing in all caps ("TYPING IN ALL CAPS") on Wikipedia, in line with most Internet resources, is perceived as "shouting" and can come across as aggressive. Please do not do it, even in edit summaries. More than occasional use of bold, italics and underline is also very 'shouty' behaviour.
