Hello

I like to put a changelog into a wiki and have the following text displayed as template *every* time I edit a specific blocks: ~~~~<br> <pre style="font-size: x-small;">

</pre> Is this possible? I played around with {{..}} and {{subst:..}} but it does not seem to do the job, subst e.g. vanishes after the first edit.

Or is it possible to launch an Extension at the beginning or end of specific edits?

bye,
