Hej there, just in case question not self-explanatory: I can always search mails received, e.g. by sender, topic, &c; but sometimes I want to look at all the mails on a topic which may be from different people and may not all have the same subject heading or key words. Can I have a set of folders (ideally expandable as needed) within the in-box, or elsewhere but accessible in Thunderbird, where I can file copies of mails by topic / group etc. ? Sorry if already in instructions and just too dim to notice. Incidentally, I could not find a database of past questions answered to search, though I feel sure that must exist somewhere and I have probably been too blind to spot that as well. Thanks for help, Old Gobbo
