This seems to be a common problem:
When you write a web address at the end of a sentence, should you follow it with punctuation, or use no punctuation? If I use punctuation after a URL will it break the web link or send people to the wrong web address?
For example, should I write…
Who likes www.chow.com?
or just
Who likes www.chow.com
??
In years past this was a real problem, but these days you can stop worrying about it.
Using Microsoft Word, Gmail, Outlook, etc., punctuation will not cause a problem with your links — the software will create an accurate link for you, in spite of any punctuation that follows it.
