Is it possible to automatically incorporate a user signature within a template (not a template within a signature) - for example, on a non-talk page, the user employs a template like {{Journal|some journal text}} that formats their entry according to the template but then auto-adds a signature as well? I tried --~~<includeonly></includeonly>~~ but that just prints the tildes themselves, doesn't resolve to the signature. Any ideas?

This is only possible if you subst: the template ({{subst:Journal|some journal text}}). See the subst: modifier in Help:Templates.
