From Lexicanum

The example here uses the <sup> tag; does anyone have any objection if I use <ref> instead? (example on my userpage) Marasmusine 19:33, 29 July 2008 (CEST)

YES! Sorry, but the ref-tags slow down big pages and in the past have led to the inaccessibility of certain ref-heavy pages. That's the reason why they are banned and have been replaced with sups. --Inquisitor S., Großmeister des Ordo Lexicanum 19:58, 29 July 2008 (CEST)

Okay, thanks for the prompt reply. Marasmusine 10:28, 30 July 2008 (CEST)
