Rather than having a separate post for useful soulmelds, you could come up with a rating system built into each meldshaper's post, similar to the one gorfnab used for Mysteries in his Shadowcaster handbook or the one Saeomon used for powers in his Psion handbook. There are some melds that are must-haves, some are situational and some are traps, and you can rate both their bound and unbound forms.
