What are some perks that people can get for achieving higher guild ranks? I'd like to hear what other guilds do, but also some new, perhaps untested ideas.

Originally, the Tahtetso made the number of guild credits you could buy dependent on your guild rank (max = 2xrank). That wasn't that popular (and plus, there were too many gr1's), and an extra 2 credits arguably wasn't a very good incentive to get some of the higher ranks. That might be brought back (with higher max limits), but I'd like something even more...

When our ninjakari get to a certain rank, we let them into our secret OOC stealth monk aether (Innerworm) which doubles as a jewelry cartel. I plan on making a set of jewelry to give a Ninjakari at each rank (perhaps ring at GR2, bracelet at GR3, necklace at GR4, brooch at GR5). Perhaps you can look into doing this?

First time I've heard of an OOC clan, but I can see that being appealing. I was thinking of some kind of sash system similar to the jewelry idea, but how do you stop other jewelers in the clan from just making stuff? Honor system? Goodness knows the Tahtetso have enough unused clans lying around right now though...

It's an OOC clan to chat/talk about stealth envoy issues. It's not required, but it's somewhere to talk and ask questions between Nekotai/Ninjakari.

As for the Jewelry question, I'm still working on that. Most of it will be honour system, but we also don't have all that many jewelers anyway. And once I design the Ninjakari stuff, it will be OBVIOUSLY Ninjakari, just like I've worked on some Nekotai designs, including a scorpion piercing needle and some prayerbeads.

Well, aquamancers are a bit reversely where they reward with rank instead of rewarding rank, undersecretaries/protectors are immediately raised to GR 5, secretaries/security are raised to GR 10, for us, rank has a reward in credits, we can all only buy ten credits a year (unless you have a perk like undersec or sec) but the higher the rank the lower each one costs.
