Apologies to the smart guys! I have downloaded Thunderbird, which seems only available in the tar.gz format that I normally avoid. When I clicked the file, I got a lovely selection of files and directories, none of which provided that elusive executable, nor a readme file on installing for dumbos like me. I'm sure some folks are sick of hearing questions about this, but please will one kind soul point me at a link or FAQ to help me do the necessary? Long scripts I cannot manage, nor detailed IT-speak relating to console commands.
Thanks a £m/$b,
OG.
