It is common for people to spend money to test but fail to do the free things that make their testing worthwile. Those free things include:
1. Uploading your results to public databases like GEDmatch (for auDNA i.e. Family Finder, AncestryDNA, or 23andMe), YSearch (for Y-DNA), and MitoSearch (for mtDNA).
2. Adding your GEDmatch, YSearch, and/or MitoSearch IDs to your DNA Tests page in WikiTree
3. Communicating with your matches (sharing your ancestral tree url) and inviting them to join WikiTree.
