Good answers! Let's try organizing them here. Firo, you're welcome to join as long as you can help out - I think we should try to have as many members as possible, but only a few will be assigned to each job; OOC, this will let the thread progress faster, and IC, this won't be wasting resources

Do try improving on the ideas below, and we could start on a set of tenets to follow!
1.
Tenet the first. What this organisation (Might want to think about finalizing the name!) seeks to achieve.Where the Knights cannot help, we will be there. We shall help all citizens of Syliras.
Expansion: I'd like to add on to this - the above is mostly a generalized one just to "show off" to the Sylirans. I feel that a job that requires killing will have to be on a case-by-case basis - more so for potentially illegal acts, as defined by the Knights. Other jobs shouldn't be too menial - whitewashing a fence? Doing laundry? - as there will be other more significant problems. Such menial jobs would have to be rejected most, if not all, of the time.
2.
Wilderness SurvivalYep, NPCs look like the way to go. Basic-level PCs - Wade - wouldn't be able to help much. Crypt could help with some of it, being closer to Competent level than Wade is, but not much at all.
3.
Relationship with KnightsI prefer to think more of ourselves as sort of the people the Knights may outsource some of their less-interesting-but-still-important jobs to.
Sounds good! So the Knights could, from time to time, decide on jobs to be allocated for the organization to do, and relay it to Ronan. Ronan, a problem with being the liaison is that Ronan would have to stay in Syliras most of the time - it might affect your trading. If possible, if it adversely affects your income, we could have Ronan as a paid 'employee' in the organization - you could have your own cute secretary. ;D
4.
HeadquartersAn apartment to start from would be best - we'll PM Accolade once this organisation gets into shape to see if we could get one. Worst case scenario, PCs'll have to pool their money together to purchase one from the
Housing Authority. I'm sure some of you members would have permanent housing in Syliras, so that could be something to work from.
5.
IncomeYeah, donating some funds would be excellent. I believe what Genryuu mentioned would be best - we could change that later on. Let's make it something to work towards for now.
6.
MasksBoth of you have excellent points there, Genryuu and Ronan. But I'd suggest going with something not
so fearsome, but something easily noticeable. Unique masks could help with identifying people. But there's a slight problem with using masks in public - connecting with the public will be harder, since they can't put a reassuring face to the members that help them. I'd suggest something else, like a brightly-coloured decorated sash or headband or bandana, but it's up to you all.
I was wondering... Accolade! If you're reading this, could the
Rogue Knight be somehow involved with this?

By the way, Genryuu, you might want to start a Plotnotes thread
here to start keeping track of all we've discussed before. It's a good place to start, and we'd best start now before this thread runs to a hundred posts!
As for the problem with inactive PCs, I propose we wait a duration of a season before kicking their names off the members' register. Thoughts?
I think that's all we need for now. This is just to see who's been keeping up with the thread and is still interested. Cheers! Good night!
