“please use”, "use", “you must use”, or …? [duplicate]
This question is an exact duplicate of:
It's a web-app. Something like GitHub for translators.
The user cannot proceed to the next action unless he selects some specified fields.
In general, which phrasing is better to use? We have a couple of similar sentences, for username, file size, etc. I want them all to be phrased in the same manner, but I struggle which one sounds better.
For example:
Please use at least 7 characters
You must use at least 7 characters
Passwords must be at least 7 characters long
Use at least 7 characters
or something else?
