... Welp some time after posting I went into making said userscript and stayed up the rest of the night.
https://logfaqs.com/misc/linkfaqs.user.js
If you have the Tampermonkey add-on just click the link and install. I only just made it up now on Firefox but should be good to go... this is the first I've publicly made one though so who knows.
- Occurences of [t:{tid}] where {tid} is a topic ID will become links to the corresponding LogFAQs archive page
- E.g. Posting '[t:77711004]' becomes a link to *lfaqs*/topic.php?id=77711004
- Ditto goes for [p:{pid}] where {pid} is a post ID.
- As mentioned, quoting posts on LFAQs is already set up to use these tag links.
- Tags are coloured red for post tags and purple for topic tags... kinda just based on my own custom GFAQs css I use so feel free to tweak that value of the script in Tampermonkey - Ctrl+F 'darkred' and you can figure out the rest, it's not a large script!
- On GameFAQS, the topic list will have an added button on that "Post New Message" bar that links to the board's LFAQs archive. Similar button appears within GameFAQs topics themselves linking to their LFAQs topic, and of course a GFAQs post page to the LFAQs post page.
Now to try and get some sleep!
