It has been 10 years since I used Thunderbird (Thunderbird Setup 3.1.9) and here I am back again (Thunderbird Setup 45.4.0) I ''think'' that back then when I replied to an email, Thunderbird inserted the sender's initials before each paragraph so that a reply to an email from, say, Paul Reynolds was quoted as:- '''PR> '''Chris, I think that your memory may be fading. I have had a look through "Options" and "Account settings", but I don't see any obvious setting, especially a Checkbox switch. A search of topics in the forum turned up nothing, but there again I am still finding my way around the forums. I would appreciate learning:- (1) Was this indeed a feature of Thunderbird? (2) Is it now a feature of Thunderbird and if so (3) How best might i trigger it to take effect. A hyperlink to an existing solution would help me in two ways:- (1) It would solve my immediate problem and (2) It might help me to know how to go about locating an existing answer to my next problem! Thanks Chris (Paul Reynolds) Greaves.
