Q: I've used LinkedIn, the social network for business people, for years. But I'm having trouble removing myself from LinkedIn Groups I was once associated with. The instructions I've found online haven't worked. What can I do?

A: You can remove your affiliation with a LinkedIn Group (typically a collection of people in the same industry or with specific shared interests) by going to the group's LinkedIn homepage (see tinyurl.com/y2a22w3m). That, in turn, will cause your affiliation with the group to disappear from your LinkedIn page. (Note that this works on the LinkedIn website, but not in the LinkedIn app for mobile devices.)
You can also go further. While on the group's LinkedIn homepage, you can delete any remarks you may have posted to a group's comments or discussions (see tinyurl.com/yyv5kyrk).
Alternatively, you can remain in a group but choose to have a looser affiliation with its members by either "muting" or dropping out of group-related conversations (see the first website.)
Note that, unless you are a group's "owner" or "manager," you can't change information for the group as a whole or for other individual members.
But, before altering any settings, read about the changes LinkedIn made to its groups last year in hopes of stimulating more interest in them (see tinyurl.com/y2l77j3e).
Q: I use Microsoft Word and Excel on a Mac. Previously I could attach an unsaved Word document or Excel spreadsheet to an outgoing e-mail simply by opening the "review" tab and clicking on "mail." But, perhaps because of a recent update, that no longer works. The new e-mail opens, but nothing is attached to it. What can I do?
