This morning I streamlined the R-L21 Plus Project a bit. I added a couple of categories for new SNPs (they have to make it to ISOGG's Tree before I will create a category for them). I also dropped almost all of the categories based at least partly on negative results: you know, "positive for this, negative for that". Those were too time consuming and difficult to maintain. Instead, each major branch SNP category carries an admonition to check for that branch's downstream SNPs, and there is an easy-to-follow pedigree for each category, like this, for example, in the case of L513: L21>DF13>L513.

The only categories I retained that are partly based on negative results have to do with the DF13/DF63 split: category "B. L21+, DF13- (If you can, test for DF63 status)" and category "Bb. L21* (DF13-, DF63-)".

If you were in one of the categories partly based on some sort of negative result, your entry has been merged back into the category for your current terminal SNP.

Gone too is the category that attempted to collect all of the guys who have tested negative for all of the currently-known DF13+ SNPs. Such info might be nice to have, but keeping track of exactly who all has tested negative for what, especially with the advent of Geno 2.0, is just too big a job in a large project like R-L21 Plus.
