"Project tagging" under way: 3002 tags total, that's average of 1.23 per font, 1781 general tags assigned (like colour, etc.), 896 external links, 325 authors/artists. There are still 1703 fonts without external links and 606 fonts without any tags.
P.S. Recently I added the "game" tag (assigning fonts from games, any platform). If anyone finds game fonts I missed, don't hesitate to suggest it.

2400+ fonts, well over 600K website visits total.

@Zbeng: links deleted.

I went over the fonts in: https://bmf.php5.cz/index.php?q=sw-
In all of them the link to https://demozoo.org/productions/181447/ needs to be removed and not replaced with anything. The other link(s) are already there.

@Zbeng: So should I batch-replace the bad link with a correct one? If I understand it correctly. If so, could you provide the correct link (to SOWATT)? Thank you.

I think you are correct that they are all related to SOWATT. Maybe by mistake I gave all of them an external link suggestion with 2 links concatenated?
Is this possible?
Anyhow the link to https://demozoo.org/productions/181447/ is irrelevant to all of them, AFAIK

@Zbeng: These 20 are all the search result (in my last comment).

If you can mail me the list of 20 fonts, I can try to figure it out.
I don't remember suggesting this external link that many times.

@Zbeng: Looked it up in the database and this URL is linked to 20 fonts, all of them begin with sw-*.
https://bmf.php5.cz/index.php?q=sw-
Maybe instead of it there should be a link to the "SO WATT" demo?

This shows up in many fonts external links:
https://demozoo.org/productions/181447/
Is this some kind of a bug?
