3. If you want to nominate yourself go ahead. Just make sure to back it up with video or with info on who you've beaten/things you've done to advance the character. I already know of your combo bread so that's one point in your favor, I don't however know which of those combos are important to peacocks combo theory nor if you are the one who made them up... So if you want to, post up the combos you made up. Know that however, some combos aren't going to get you onto the list... They just help. You still need to show decent playing ability outside of making combos.
Or, if a couple of listed players vouch for your strength (with examples of high level players you've beaten), then you can bypass that entire thing and get listed "easily".
Though to be honest I don't really want to add in anyone where little to no video representation of there play is available.
There is video of every player currently on the list, owning people.
