Here's a suggestion:

General TSU-Suggestions

Lets all try to use proper phone number formatting so the numbers are easier to read correctly (might reduce or eliminate dialing innocents by mistake)

For US numbers, for instance, use (123) 456-7890 or 123-456-7890
instead of 1234567890
It might help a little?

I wouldn’t consider this a tsu suggestion since it’s not something we would implement on the forum but more of a suggestion to users as a common courtesy.
