I log every match I find on Gedmatch, FTDNA and MyHeritage for myself and my siblings. I include the chrom. the segments, if there is a gedcom, a link to a family file if I find one, the Wikitree ID, relationship if identified, with ancestor ID's from Wikitree if identified, 3-way or more matches are highlighted in a specific color, matches are identified as being paternal or maternal if known, relationships are coded - P8c1 as an example, e-mails, notes on everything, a note if I have sent an e-mail with the date and a note if there is a significant response. "I think Wikitree is creepy" an actual response - tells me I probably do not need to get anymore information from that person.
The data is sorted by name, chromosome, segment but can be sorted as needed.
