I was just thinking about this other day. Of course, there are endless permutations of parameters one could put into listing achievements. Also, one may have highly personalized achievements that may be personally meaningful but difficult to compare.
I agree with fortknox and don't think there is a need to administer/validate a centralized listing, but looking at one's achievements is a neat concept to talk about.
Some of my favorite personal achievements were taking a 3-way draw with Babak and MadMarx in one of the Anonymous Blind Invitational games, and 3-way draw with MadMarx and TheWizard at the WebDip Boston FTF Tournament. I'm also quite happy that I came back from 1 SC, lasted several more years, and made it to the draw in the Anonymous Blind Invitational Championship game.
Here are a few general ideas:
(Of course one could customize these for specific/favorite game params, and/or only consider them achieved in legitimate games that aren't ruined by cheaters or quitters, etc.)
=Solos=
(First, 10, 100, etc) solos
Solo before year (1915, 1910, etc)
Solo with each power
Come back from 1 SC to solo (The Czech has done this very convincingly)
=Draws=
Legitimate race-to-line 2-way draw in a WTA game
Come back from 1 SC to draw
Finish in the draw holding only 1 SC
=Stats/Rating=
Maintain >X% (40, 50, 60, etc) Win+Draw ratio over first (25, 50, 100) games
Reach the top (100, 50, 10, 1, etc) in GR
0 (or >1%) Resigns
Complete 1000 games (I think only The Czech has done this, but Lando is getting close)
=Misc/Other/Consolation=
Play at a WebDip Face-to-Face tournament
Win a WebDip tournament
Last for more than one year in purgatory (0 units, 0 home SCs, >0 non-home SCs)
