Paragaya,

Is there a reason for posting this information here instead of encouraging people to use the built in tagging system for TinyPortal 1.0 beta 4?

ZarPrime, in the source you see in the first lines the info about a TAG-CLOUD. Imho TP hasn't that as a feature build in? Anyway, his posting is here in the german section a bit wrong I think.

PowerPyx,

Yeah probably.  Anyway, I think there is a tag cloud block code snippet somewhere in the snippets board, but I can't really be bothered to look for it right now.  Perhaps I'll stick this code on one of my test sites and see what it does.  If it is productive then I'll move it to the block code snippets board.
