A while ago, I wrote a tag wiki for the [dsp] tag on SO. Later, [dsp] became a synonym for [signal-processing]. However, nobody has written a tag wiki for the latter. Is there any way to retrieve the text of the [dsp] wiki and transfer it to [signal-processing]?
Yes! Well, you might not necessarily be able to do it directly yourself. But 10k users have access to a new feature in their tools which lets them see wiki posts. Wikis for tags which get eradicated end up as "orphan wikis". These users can read those wikis and then collect the text contained within.
However, there are two things to note:
- This wasn't immediately available when tag wikis were first established. So if it is a particularly old wiki (like what happened here), then there is no orphan.
- There is no visual indication of what tag any particular orphan wiki is for. So it may take some time for someone to find the right one. If you can remember the date you created the wiki, then it can help as the entries in the tool are listed in reverse chronological order.
As an example, this is the orphan wiki for the old always-friday-in-iceland, which became a synonym for fun. No guarantees on the visibility of that link, though, but if it's anything like the FAQ revision history then anyone can look at it.
