I'd been sitting on the fence here for a while, because it's not really a topic I had considered until now. I was always under the impression that all JS got access to O5 and that was completely okay. If it's only certain team's JS getting access, that's simply not fair and needs fixed. I will also note that it's kind of funny coming from Cimmerian about this and other's expressed concerns about JS visibility, considering how long he flew under the radar as JS. That's not a mistake that I want to repeat if at all possible.
However, after reading Nusquam and Roget's arguments, I feel that there could potentially be changes to how both the Wikiwalk team and Licensing (as well as others that need it) do things to both facilitate having somewhere to organize their work, and to be more fair to the JS on other teams who traditionally have not been allowed to perform their work on this site or participate in discussions except by proxy.
For instance, the licensing team will soon be performing a recruitment drive to get our attribution and image licensing in order. With the potential number of new recruits and the magnitude of the task, in addition to expected burnout, I believe that setting up a licensing wiki would be the best way to go about solving that particular problem. The wikiwalk team could do something similar. Or we could even share a site and just use separate subforums, to save real estate and because I have no idea at this exact moment how to make a wiki and would love the help. Then, both teams could just share anything super important that we come across (e.g., a copyright claim against us in images/licensing, big offsite projects like a SCP tv series getting greenlit, new additions to the crosslink project, etc.) by writing up reports here.
Now, I'm going to publicly address the letter that was sent to me by one of my own JS about this subject:
This is not in any way going to affect your (or any other member of my team, or any other)'s advancement. In the event that all JS are moved off of O5, yes, there will be some visibility issues. However, promotions are based entirely on your own work and your teammates/captain's recommendations, and while participation in discussions helps to gauge your personality and other qualifying things such as temperament, it's not strictly necessary. If a team's captain wishes to see their JS promoted further up the ladder, but others do not understand or see the contributions that are made, then I believe that that would be a failure on your team captain's part to adequately promote and explain your contributions. This is a common problem in the less visible teams who do most of their work either off-site or behind the scenes, but can be solved relatively easily by captains and full staff on teams actively working as "hype-men" for the JS that do good work.
All site members are allowed to chime in on any discussion that they wish on O5, to my knowledge, and I have always taken information and input from non-staff and JS into consideration when they come to me about something. If you wish for your voice to be heard, then please, speak up, and go to someone who can post to the site for you.
TL;DR version: I believe that making a separate wiki for the Wikiwalk and Licensing teams, and writing up reports either regularly or when necessary to O5 is the best way to address this situation if we do not want all JS access to this site/to participate in discussions. I also believe that if we do bar JS from participating directly, that captains and other staff members will need to step up and make sure that their JS teammates are not flying under the radar when they do good work come promotion season, and that their voice is heard when they have relevant insight to a situation.
