Also you can ask mods to turn a topic into wiki mode where anyone with TL1 can edit.
Anyone with TL1 can create and append tags to a topic, so I would use something like rfc-cycling in all related topics. This would allow you to link them all (and get notifications on new ones) in one step.
Restrictions should be applied only when needed and on actual cases where it is needed. Applying such restrictions ‘a priori’ is just message to us that we are idiots that need to be controlled. This just reduces usablity and complicates organizing content.
Let people be and freely communicate and contribute. If someone makes problems, handle that person. Requirement for category to be opened is that there are three moderators appointed. That is more than enough to handle people who behave oddly.
That is my opinion based on 30 years of actively participation in administering mail lists, newsgroups, forums, and various social media sites.
I hope that there is no option to also automatically close topic after some time.
My understanding on edit time limit defaults is that it protects from a spam technique that consists in posting normal messages for a while and after sometime edit them to include spam, this will pass unnoticed since the topics are not bumped.
If editing a topics for longer than 1 month is something that is often needed, moderators can be asked to turn the topic into a wiki message (so it was always be edited).
Alternatively TL2 post edit time can be increased or unlimited.
I would avoid modifying the TL0 and TL1 restrictions to keep this spam protection I mentioned in place.
Is this really needed? Has spam been a big problem in the old forum? Could we try without and put it back in place when needed? Because people using the forums mainly via email are discriminated against by this rule.
This is a known spam attack vector for many Discourse forums, that’s why TL0 and TL1 have this limitation. Accounts are created, a few normal messages are posted and then after a while edited to include spam links.
If you use the forums via email, you don’t really need the advantages of TL2, because they only apply to web ui actions (like edit). If you often need to edit from the web ui, then you’ll get TL2 easily.
Does this include people who read via email? Each email often has links to images. If your email client loads then, then the discourse software could track that. I presume not, but it would be good to check
