I sometimes get private messages from people who just want to say hi or say thanks. It’s annoying that “Thanks!” is too short for responses to private messages.
This can be changed via the
min personal message post length site setting I believe
The post length requirement for PMs can be configured by the site admin, the setting is called
min personal message post length and by default it’s a little shorter than the minimum public post length requirement.
Sometimes people find short messages like “Thanks!” annoying (did this need to be a message at all? maybe the like button is enough!), so the default is to require someone to put a little effort into their message before sending it to someone.
Okay thanks, I’ll ask the people who manage the site in question.
This is also why I specified responses only. I think the minimum length is very reasonable for the first message in a PM thread.
