That's no different to how Spirituality is now.
In fact...
I believe the key point would be to find a technique/reason to incentive writing those.
It might seem more or less a themed 'journal' from a certain viewpoint... and yet sometimes cool things may pop even by 'asking around'.
I believe also that certain things to be written need both knowing very good what you know, and to know how to write it down. In the case the second may be slightly lacking, I suppose a guide (or sorta) might be helpful. For example: a while ago I remember we were answering to a chain of questions/questionnaire. It was quite general, but still something for maybe who doesn't have a lot to say in the first place, or is finding some troubles expressing.
Though returning to the whole singular topics...
Why not sticking/archiving the material we already have now, for a start?
Or maybe starting by browsing with the draconity tag? (or adding that tag to specific posts, like tag hunting topics?)
Or was this section meant to be written 'as anew'?

Regarding the present spiritual forum, and on a parallel activity, I'm quite curious to know if new users are, or would, or how, be interested in such things. Like asking as a question community wide... not sure which question specifically, maybe something like 'what would you expect from a spiritual viewpoint to be discussed', or if ever 'expecting anything spiritual to be discussed at all'?
Or was this question already asked before?

Again for general promoting on the field:
What about making replicas of those IRC chats scheduled sessions we had time ago, regarding spirituality?
(now now, all these ideas seems to mess up a bit all of them in a single post...)
