OK, so I reread the thread and came up with the following:
Kunoichi - Succubus - 6 racial HD + 6 class levels + 0 LA
ExisD - Succubus - 6 racial HD + 6 class levels + 0 LA
PaleEnchantress - Nymph - 6 racial HD + 5 class levels + 1 LA, wizard spellcasting substitution approved
Zaer Darkwail - Vampire Changeling - 0 racial HD + 10 class levels + 2 LA, you can take vampire lord later
TheGlphystone - Unbodied - 4 racial HD + 8 class levels + 0 LA, extra feat at level 1, 4 extra skill points at level 1 + 1 extra skill point per level thereafter, +2 to two ability scores of your choice
For monsters with racial HD, base stats are those given in the monster manual. Then, add/subtract the following (+4, +3, +2, +2, +0, -2) to the ability scores of your choice to simulate an elite array. At 4 HD, 8 HD and 12 HD you get the usual +1 to an ability score of your choice. However the monster manual entry is assumed to already include the increases from existing HD. For example succubus only gets +1 for 8 HD and 12 HD.
For races without racial HD, use the elite array (15, 14, 13, 12, 10, 8) as the starting point and work from there.
You get feats at 1st, 3rd, 6th, 9th and 12th HD, some of which may be accounted for in the monster manual entry if you have racial HD. You are free to swap those out for feats you actually want.
If you are interested in joining but your name is not on the above list, you need to come up with a character idea so that it can be (dis)approved.
